In general, in loom, comprise the fabric winding device that the fabric after weaving is reeled.

Specifically, have the fabric after weaving is wound on the cloth rewinder roll by work beam and pressure roller etc., thereby on cloth rewinder roll, form the fabric winding device of yardage roll.

During to fabric wrapping, have the necessary set tension force that is used to reel by the coiler device of this kind fabric on the fabric before coiling, uneven tension force becomes the reason that produces the volume wrinkle on the fabric after just being winding on the cloth rewinder roll in the fabric.

Therefore, the fabric winding device of existing loom comprises the anti-locking mechanism of volume wrinkle that produces the volume wrinkle on the fabric that is used to prevent after just reeling mostly.

As first prior art, for example Fig. 6 has shown the key component of the fabric winding device that has comprised the anti-locking mechanism 51 of volume wrinkle.

The anti-locking mechanism 51 of volume in this fabric winding device wrinkle mainly by extend abreast with respect to cloth rewinder roll 53 and be arranged on yardage roll R and reel before fabric W between the depression bar 52 of round bar constitute.

Depression bar 52 will utilize the crimp force of cloth rewinder roll 53 sides that produced by the guiding of fabric W simultaneously from the fabric W of pressure roller etc. to cloth rewinder roll 53 guiding, and the side face of yardage roll R is pushed (for example referring to Patent Document 1).

And, in Fig. 6, represent the state of depression bar 52 to the coiling direction bending by solid line, shown the state that on yardage roll R, produces volume wrinkle S owing to this bending.

In addition, in Fig. 6, represent not have the depression bar 52 of case of bending by double dot dash line.

And, as the 2nd prior art, for example comprised that the fabric winding device of the anti-locking mechanism 55 of volume wrinkle shown in Figure 7 is known.

The anti-locking mechanism 55 of this volume wrinkle is to be the side face 58 of circular arc and the shaft-like push part 56 that tabular surface 57 constitutes by the cross section mainly, and push part 56 has the roughly cross sectional shape of circular segment.

Push part 56 extends in parallel with respect to cloth rewinder roll 53, and the tabular surface 57 that push part 56 is had contacts with the side face of the yardage roll R of cloth rewinder roll 53 sides, and the cross section is that the preceding fabric W of 58 pairs of coilings of side face of circular arc leads.

Summary of the invention

In the 1st prior art, owing to use round bar as pressure roller, pressure roller is supported by both ends, thereby the necessary fabric tension of reeling applies the power that makes it to the coiling direction bending to pressure roller.

Have the bending that results from pressure roller and help to roll up the problem that wrinkle produces.

Particularly, form in the situation of wide cut at fabric, the axial length of pressure roller and the ratio of diameter increase, and at this moment, have born the easier bending of pressure roller of fabric tension.

In the 2nd prior art, because the week of push part is in the face of the fabric channeling conduct before reeling, and the tabular surface of push part carries out crimping to yardage roll, therefore, gets the nod with respect to the advantage that the contact of the face of yardage roll can realize preventing rolling up aspect the wrinkle in push part.

But, because the cross section of push part is roughly circular segment, for example making by round bar in the situation of push part, must implement to form the machining on plane, carry out chamfer machining near tabular surface and side face are had a common boundary, eliminate that to be accompanied by processing formed crooked etc., the problem of push part can not be conveniently made in existence.

But also there is the problem of determining by push part middle section arc diameter by fabric from pressure roller to push part and the formed guide angle of the fabric from push part to cloth rewinder roll.

Though for example can expect to improve the effect of push part to the crimp force of yardage roll by reducing guide angle, in this case, in order to have reduced guide angle, area that can only tabular surface descends, and perhaps increases the arc diameter of push part.

Reduced tabular surface and will cause preventing that volume wrinkle effect from descending, and the arc diameter of increase push part will cause problems such as push part maximization and weight increase.

In the 3rd prior art, contact with yardage roll though disclose a plurality of rollers, because all rollers all are separate rollers, the possibility height of a roller to yardage roll enforcement crimping only arranged, may not fully prevent the volume wrinkle.

And owing to be supported independently of each other roller, still exist the roller that at least fabric is led to bear tension force and to the problem of coiling direction bending.

In view of the foregoing, propose the present invention, the purpose of this invention is to provide a kind of fabric winding device of loom, except can preventing reliably that the volume wrinkle that is easy to generate when the fabric wrapping from taking place, compared with prior art, can make the anti-locking mechanism of volume wrinkle simply.

The specific embodiment

(the 1st embodiment)

Hereinafter will describe the fabric winding device (hereinafter referred is ' fabric winding device ') of the loom of the 1st embodiment according to Fig. 1～Fig. 3.

Fig. 1 be expression the 1st embodiment fabric winding device 10 the side view of major part.

The fabric winding device 10 of this embodiment as shown in Figure 1, mainly comprises expansion link 11, work beam 12, pressure roller 13, cloth rewinder roll 14, the anti-locking mechanism 17 of volume wrinkle.

Expansion link 11 is bar-like members that the fabric W by the loom manufacturing is led downwards from horizontal direction.

Work beam 12 be with the fabric W after leading downwards by expansion link 11 once more upward, towards the roller that pressure roller 13 leads, work beam 12 and pressure roller 13 become carry out the roller of cramping by the fabric W between two rollers 12,13.

Pressure roller 13 is to make the roller towards the cloth rewinder roll 14 of below towards the fabric W of top.

Cloth rewinder roll 14 is rollers that the fabric W that comes from pressure roller 13 guiding is reeled, and cloth rewinder roll 14 links to each other with the drive source (not shown) with cloth rewinder roll, and rotates along the direction that fabric W is reeled.

In this embodiment, the fabric W that exports downwards from the front side of pressure roller 13 is wound up on the cloth rewinder roll 14 through the rear side of cloth rewinder roll 14, forms yardage roll R on cloth rewinder roll 14.

And expansion link 11 and each roller 12～14 are except having than the big length of the width of fabric W, and in the mode that each axle center is parallel to each other, expansion link 11 and each roller 12～14 two end axles are bearing on the side frame (not shown) of loom.

Hereinafter will the major part of the anti-locking mechanism 17 of volume wrinkle be described.

The anti-locking mechanism 17 of the volume of this embodiment wrinkle, as shown in Figure 1, have be arranged on yardage roll R and reel before fabric W between and welded part 18 that contact with yardage roll R and the guiding parts 25 that the preceding fabric W that reels is led.

In this embodiment, welded part 18 is equivalent to roll up the pressure contact portion of the anti-locking mechanism 17 of wrinkle, and guiding parts 25 is equivalent to roll up the guide part of the anti-locking mechanism 17 of wrinkle.

Be provided with the swing arm 15 that rotationally two ends of guiding parts 25 is carried out the axle supporting, the upper shaft of swing arm 15 is bearing on the fulcrum shaft 16 that is arranged at work beam 12 belows.

Thereby even be formed on yardage roll R enlarged-diameter on the cloth rewinder roll 14, swing arm 15 fascinates corresponding to the diameter of yardage roll R, and the anti-locking mechanism of volume wrinkle rotates with respect to swing arm 15, thereby can keep the crimping of the anti-17 couples of yardage roll R of locking mechanism of volume wrinkle.

Welded part 18 and guiding parts 25 are by as shown in Figure 2 as the bolt 23 of connect mechanism and link to each other mutually.

Now welded part 18 is described, welded part 18 is the tubular parts that extend abreast with respect to cloth rewinder roll 14, and its cross section is Long Circle roughly.

Welded part 18 length setting in the longitudinal direction must be bigger than the width of fabric W.

Thus, form the recess 19 that does not contact, have point of contact 20 respectively in the both sides of the cross section of recess 19 major diameter direction with yardage roll R along the length direction of welded part 18.

Promptly, has in the week of yardage roll R the contact point 20 that contacts on (hereinafter being called the circumferential of yardage roll) a plurality of positions that make progress on the welded part 18.

Because contact point 20 forms continuously along welded part 18 length directions, thereby broad ways contacts with the side face of yardage roll R.

Because recess 19 and contact point 20 are towards the side face of yardage roll R, the cross section is that oblong welded part 18 has flat pattern, sets at the circumferential size ratio of yardage roll R big in the size of yardage roll R radius (hereinafter being called the yardage roll radial direction).

This is preventing because the tension force of fabric W causes that this one side of bending of welded part 18 is very effective.

And, be that oblong tubular part carries out press process and can obtain recess 19 on the welded part 18 by pair cross-section.Specifically, by to carrying out pressurized near the center of oval tabular surface, can form recess 19 fairly simplely.

And on recess 19, keeping set compartment of terrain to form a plurality of peristomes 21 along welded part 18 length directions, the area of peristome 21 is set at the area that the head 23b of bolt 23 can pass through.

And, on welded part 18,, on the position relative, offer the through hole 22 coaxial with peristome 21 with peristome 21 relative with guiding parts 25 and do not form on the tabular surface of recess 19.

The aperture of through hole 22 is set at bigger than the diameter of the axial region 23a of bolt 23, and is littler than the diameter of the head 23b of bolt 23.

Thereby, bolt 23 can be inserted in the welded part 18 from peristome 21, make the axial region 23a of bolt 23 side-prominent to guiding parts 25 from through hole 22.

In this embodiment, distance between peristome 21 and the through hole 22 be set at the head 23b length in the axial direction of bolt 23 much at one, so that realize that the head 23b of bolt 23 is not outstanding from peristome 21, this is that the head 23b of bolt 23 does not interfere with yardage roll R when carrying out crimping for the side face at 18 couples of yardage roll R of welded part.And by form peristome 21 on recess 19, the edge portion of peristome 21 does not contact with the side face of yardage roll R.

Hereinafter will describe guiding parts 25.Guiding parts 25 is the round bars that extend in parallel with respect to welded part 18 on the yardage roll R radial direction outside, and guiding parts 25 is arranged on from welded part 18 on position outstanding outside the yardage roll radial direction.Guiding parts 25 is bigger than the width of fabric W at the length setting of length direction.

Shown in Fig. 2 and 3, on the side face of guiding parts 25, with the tabular surface opposite side of welded part 18, run through being provided with the bolt hole 26 corresponding respectively with the through hole 22 of welded part 18.

Bolt hole 26 is the screwed holes that comprise the negative thread corresponding with pin thread on the axial region 23a that is formed on bolt 23.

And in this embodiment, the bolt 23 employing hexagonal fastening bolts as connect mechanism have formed die nut hole 23c on the head 23b of bolt 23.

Because guiding parts 25 is round bars, the part of guiding parts 25 side faces constitutes the spigot surface 27 of preceding fabric W to cloth rewinder roll 14 channeling conducts of will reeling.

And on the side face of guiding parts 25, left and right symmetrically has formed along with towards the coiling direction of fabric W and a plurality of tippers 28 that enlarge laterally on guiding parts 25 length directions.

Described tipper 28 is gone up the tension force that produces with fabric W and is combined, make fabric W to the expansion of the both ends of guiding parts 25,, promote the even tension on the fabric W on width because fabric W expands, combine with the crimping of 18 couples of yardage roll R of welded part, produce so that prevent the volume wrinkle.

It is little that the diameter of the guiding parts 25 of this embodiment (length that guiding parts made progress in yardage roll week) is set at the length that makes progress in yardage roll week than welded part 18.

Reason is to avoid at the fabric W that arrives guiding parts 25 from pressure roller 13 and from the shape set of formed guide angle X between the fabric W of guiding parts 25 arrival cloth rewinder rolls 14 by welded part 18.Just, if increase the length that welded part 18 made progress in yardage roll week in order to prevent to produce the volume wrinkle, then the diameter of the guiding circular arc face of guide part also increases in the existing structure, then guide angle X also increases, but structure according to present embodiment, because guiding parts 25 is littler than the length that welded part 18 made progress in yardage roll week in the length that makes progress in yardage roll week, can contain the increase of guide angle X.

And, except reducing guide angle X,, increase the crimp force of 18 couples of yardage roll R of welded part according to the tension force of fabric W, also help to prevent the volume wrinkle.

And, guide angle X by the side face of the summit of the arc diameter of spigot surface 27, spigot surface 27 and yardage roll R on the yardage roll radial direction distance and the diameter of yardage roll R determine.

In this embodiment, because it is little that the diameter of guiding parts 25 is set at the length that makes progress in yardage roll week than welded part 18, and guarantee the distance of guiding parts 25 and formed yardage roll radial direction of being connected of welded part 18, thus, compared with prior art, can set guide angle X little.

Thereby, fabric winding device 10 purposes of this embodiment are, the shape that is had according to welded part 18 improves the intensity of welded part 18, the intensity that improves welded part 18 that is connected by guiding parts 25 and welded part 18, make guide angle X minimizingization by making guiding parts 25 and welded part 18 become the branch body component, improve the design freedom of guide angle X, and, thereby because the simple shape of guiding parts 25 and welded part 18 improves the easy degree of making.

Hereinafter the coiling action of the fabric W that will carry out the fabric winding device 10 by this embodiment describes.

Rotate by cloth rewinder roll 14, the fabric W after weaving is reeled, and the fabric W after just having weaved is led by expansion link 11, by the front side of expansion link 11, turns to the work beam 12 of below.

The fabric W that is directed to from the rear side of work beam 12 changes direction by work beam 12 and is directed to towards the top, and, between work beam 12 and pressure roller 13, turn to the guiding parts 25 of the anti-locking mechanism 17 of volume wrinkle from the front side of pressure roller 13.

Redirect to spigot surface 27 sliding-contacts of the fabric W and the guiding parts 25 of guiding parts 25, and be directed into cloth rewinder roll 14.

Be directed to the fabric W of guiding parts 25 and be directed to the fabric W formation of cloth rewinder roll 14 and the corresponding guide angle X of diameter of yardage roll R from pressure roller 13 from guiding parts 25.

Thus, the fabric W that turns to cloth rewinder roll 14 from guiding parts 25 from the downside of cloth rewinder roll 14 towards reeling ventrally.

The yardage roll R that forms by the coiling of fabric W after by firm coiling fabric W and form the side face of yardage roll R, but the side face of yardage roll R bears the crimping of welded part 18.

If carry out the coiling of fabric W by cloth rewinder roll 14, the diameter of yardage roll R increases gradually, and then corresponding to the hole enlargement of yardage roll R, swing arm 15 is that fulcrum rearward fascinates with fulcrum shaft 16.

Thus, if swing arm 15 fascinates, then the anti-locking mechanism 17 of volume wrinkle is a fulcrum shaft with guiding parts 25, rotates with respect to swing arm 15, keeps the contact point 20 and yardage roll R side face state of contact of welded part 18.

And, owing to fabric W is reeled, on the fabric W between pressure roller 13 and the cloth rewinder roll 14, there is tension force by the cramping of work beam 12 and 13 couples of fabric W of pressure roller and by the rotation of cloth rewinder roll 14.

The tension force of fabric W will be corresponding with guide angle X power be sent on the welded part 18 by guiding parts 25, welded part 18 carries out crimping corresponding to the tension force of fabric W to yardage roll R.

When 18 couples of yardage roll R of welded part carried out crimping, the contact point 20 of welded part 18 pushed yardage roll R at 2 that make progress in yardage roll week, with the yardage roll R sliding-contact of rotating.

With at 1 contact point the situation that yardage roll R pushes is compared, welded part 18 yardage roll week upwards 20 couples of yardage roll R of contact point of 2 positions push, can further prevent from the side face of yardage roll R, to produce the volume wrinkle.

Just, because the side face of yardage roll R is also passed through in the side face sliding-contact of a plurality of contact point 20 and yardage roll R, the fluctuating on the yardage roll R side face after the sliding-contact almost disappears, and the hidden danger that the generation volume wrinkles is minimum.

In addition, the tension force of fabric W makes the coiling direction bending of welded part 18 to fabric W by guiding parts 25, but owing to fully guaranteed the length that welded part 18 made progress in yardage roll week, thereby, can contain the bending of welded part 18.

And,, can prevent to cause welded part 18 bendings by the tension force of fabric W because guiding parts 25 has increased the intensity of welded part 18 by guiding parts 25 is connected on the welded part 18.

In addition, the tipper 28 that is formed on the spigot surface 27 of guiding parts 25 combines with the tension force that fabric W is produced, and makes fabric W to the expansion of the two ends of guiding parts 25, promotes by the even tension on the fabric W behind the guiding parts 25.

According to the fabric winding device 10 of this embodiment, can realize following effect.

(1) since welded part 18 in a plurality of positions contact that makes progress in yardage roll week, each contact point 20 to yardage roll R crimping equably, thereby can greatly reduce the hidden danger that produces the volume wrinkle in the front and back of coiling direction.And, be difficult to tension force because of fabric W to the coiling direction bending owing to fully guaranteed the length that welded part 18 made progress in yardage roll week, welded part 18, can prevent the volume wrinkle that the bending because of welded part 18 causes.

(2) because welded part 18 and guiding parts 25 are branch body components, the welded part 18 that the anti-locking mechanism 17 of volume wrinkle is had links to each other by bolt 23 with guiding parts 25, by the mutual binding of welded part 18 and guiding parts 25, improved intensity as the anti-locking mechanism 17 of volume wrinkle.Particularly guiding parts 25 can further hinder the bending of welded part 18 to coiling direction.

(3) owing to use the fairly simple round bar of shape, thereby by round bar is processed simply as guiding parts 25, just can easy manufacturing guiding parts 25, for example, just can serve as guiding parts 25 by existing parts are migrated.

(4) using the cross section is that the tubular part of oval shape is as welded part 18, if the face that makes oval length side is towards yardage roll R, then can realize the lightweight of welded part 18, can realize that the opposing intensity of 18 pairs of bendings that caused by the tension force of fabric W of welded part improves simultaneously.

(5) because the recess 19 that is provided with between the contact point on the welded part 18 20 and leaves with yardage roll R, the contact point 20 that separates at a certain distance by recess 19 can be provided on the welded part 18, by bolt 23 is arranged on the position of recess 19, except the existing bolt 23 of easy employing, can also avoid the interference of bolt 23 and yardage roll R.And, can prevent the damage that the edge portion by peristome 21 causes yardage roll R reliably.

(the 2nd embodiment)

Hereinafter will describe the fabric winding device of the 2nd embodiment according to Fig. 4.

Fig. 4 is the side view of wanting portion of the anti-locking mechanism of volume wrinkle of expression the 2nd embodiment.

As shown in Figure 4, the 2nd embodiment is to prevent that as the volume wrinkle volume wrinkle of locking mechanism prevents the pressure contact portion 32 of parts 31 and the example that guide part 34 is formed by 1 parts.

Thereby, to identical with the 1st embodiment or similar member, use identical Reference numeral, the explanation of quoting fabric winding device in the 1st embodiment.

As shown in Figure 4, the volume of this embodiment wrinkle prevents that the cross section of parts 31 from being roughly T font.

The volume wrinkle prevents that parts 31 from extending abreast with respect to cloth rewinder roll 14, and its length is bigger than the width of fabric W.

Volume wrinkle prevents that parts 31 from for example being the single part that can be obtained by the drawing forming that uses drawing mould etc.

Volume wrinkle prevent parts 31 have the side face that comprises yardage roll R carry out crimping smooth crimping face 33 pressure contact portion 32 and near the guide part 34 outstanding center of pressure contact portion 32.

Because the crimping face 33 in the pressure contact portion 32 is tabular surfaces, thereby contacts with the circumference of yardage roll R, but crimping face 33 also can have a plurality of contact points that contact with yardage roll R.

In other words, we can say also that crimping face 33 is included in the contact point of a plurality of positions contact that makes progress in yardage roll week.

By the length of guaranteeing that fully crimping face 33 made progress in yardage roll week, can prevent to prevent the bending of parts 31 by the caused volume wrinkle of the tension force of fabric W.

Hereinafter will prevent that the guide part 34 in the parts 31 from describing to the volume wrinkle.

Guide part 34 does not exist the face center of crimping face 33 sides (outside of yardage roll radial direction) neighbouring outstanding from pressure contact portion 32, and guide part 34 is littler in the circumferential length of yardage roll than pressure contact portion 32 at the circumferential length setting of yardage roll.

On the top of guide part 34, disposed with guide part 34 the circumferential length of yardage roll corresponding, the cross section is circular-arc spigot surface 35.

By must be littler in the circumferential length of yardage roll at the circumferential length setting of yardage roll than pressure contact portion 32 with guide part 34, and make distance become enough distances from the side face of yardage roll R to the top of spigot surface 35, thus, irrelevant with pressure contact portion 32 in the circumferential length of yardage roll, the guide angle of the fabric W that led by spigot surface 35 can be set at low-angle.

And, though not shown in the figures, the tipper identical with the tipper 28 of the 1st embodiment also can be set, to realize homogenising by the fabric W tension force of spigot surface 35 on spigot surface 35.

And, preventing that in the volume wrinkle two ends of parts 31 are provided with back shaft 36, it is by the swing arm (not shown) axle supporting identical with the 1st embodiment, and corresponding to the diameter of yardage roll R, the volume wrinkle prevents that parts 31 from rotating with respect to swing arm.

According to this embodiment, can realize following effect.

(1) when 33 couples of yardage roll R of crimping face crimping, owing to comprise the crimping face 33 of a plurality of contact points and the circumference of yardage roll R contact, thereby on the side face of yardage roll R, fabric W has almost eliminated producing the hidden danger that volume wrinkles in the upwards fully expansion of yardage roll week.

(2) if fully guarantee the length that pressure contact portion 32 made progress in yardage roll week, then since pressure contact portion 32 and guide part 34 form by parts, thereby, the volume wrinkle that has comprised pressure contact portion 32 prevents that the intensity of parts 31 from improving, and prevents to prevent the bending of parts 31 to coiling direction by the caused volume wrinkle of the tension force of fabric W.

(3) because pressure contact portion 32 and guide part 34 are formed by parts, thereby can prevent volume wrinkle on the side face of yardage roll R reliably, the while can also be controlled the number of components of fabric winding device.

And the present invention is not limited to above-mentioned embodiment, in not breaking away from the present invention's spirit scope, can carry out various changes, for example also can carry out following change.

In above-mentioned the 1st embodiment, as guiding parts, use round bar, but replace round bar with tipper, for example as shown in Figure 5, also can run through the tabular guiding parts 41 that length direction has the spigot surface 42 of circular-arc knuckle line and be installed on the welded part 18 being formed with.In this case, need not on guiding parts 41, tipper to be set, can make guiding parts 41 fairly simplely.

In above-mentioned the 1st embodiment, use is connected with welded part guiding parts as the bolt of connect mechanism, but for example also can adjust the distance between yardage roll side face and the spigot surface, adjust guide angle by between guiding parts and welded part, adjustment component being set.In this case, by adjustment, can adjust the crimp force of the anti-locking mechanism of volume wrinkle to yardage roll to guide angle.

In above-mentioned the 1st embodiment, use bolt as connect mechanism, but linking method for example also can be welding, also can be the method that is connected that can keep guiding parts and welded part at least.

In above-mentioned the 1st embodiment, the length direction that runs through welded part has formed recess, but for example also can be only recess be set partly passing on the position of bolt, forms peristome on each recess, the position except recess all forms smooth crimping face.In this case, in welded part, the contact point that contacts with yardage roll increases, and further promotes to prevent the volume wrinkle.

In the above-mentioned the 1st and the 2nd embodiment, the cross section of spigot surface is a circular arc, but can be elliptic arc also for example, comprise the different a plurality of circular arcs of curvature compound circular arc, comprise the circular-arc spigot surface of the oval arc of the straight line that links to each other with circular arc.

In the above-mentioned the 1st and the 2nd embodiment, drive source directly makes cloth rewinder roll rotate, but for example also can be to use the slave mode cloth rewinder roll of transfer members such as the gear that transmits drive source drives power or belt, and the rotating mechanism of cloth rewinder roll does not have special qualification.
