The periphery of described in the above rotor 51 is being interted for example 4 bobbins 52 cylindraceous by bobbin fixing device 1 array, and sliver Y is wound on the peripheral shape resultant yarn bar package P of these bobbins 52 respectively.And the lid member 59 on the top of the release of 1 pair of bobbin 52 of bobbin fixing device/control action by being arranged on rotor 51 moves along the axis direction of spool stand (rotor 51) and carries out.This lid member 59 has piston portion 59a, and piston portion 59a remains on the inner peripheral surface of rotor 51 with the air-tightness state by O type circle 62, can slide.And, between the top bump 51a of piston portion 59a and rotor 51, be inserted with spring 64 by spring perch 63.By this structure, lid member 59 is by the pressuring direction along arrow a, the diameter of each clamping component (chuck piece) 3 each shading ring 2 that passes through like that as hereinafter described enlarges, each clamping component 3 is squeezed on the periphery cylindrical portion 59b of the lid member 59 with shading ring function, disposes along axis direction.Therefore, bobbin 52 quilts are being held on the spool stand 50.And when with bobbin 52 when spool stand 50 discharges, the pneumatics chambers 65 from the through hole 56a of axle drive shaft 56 in the rotor 51 import pressurized airs.Thus, the elastic force that lid member 59 overcomes spring 64 is compressed along the direction of arrow b, and the reduced of clamping component 3 discharges bobbin 52 from spool stand 50.Lid member 59 grades are the shifter of the action/non-action of clamping component 3.
The bobbin fixing device 1 of this example is arranged on the spool stand 50 of above-mentioned example explanation.Below, describe this bobbin fixing device 1 in detail.
As mentioned above, Fig. 1 has represented the section-drawing of the main portion of bobbin fixing device 1, and this bobbin fixing device interts in the periphery of rotor 51, has a plurality of shading rings 2 and the clamping component 3 that are cross-linked configuration along the axis direction of rotor 51.And clamping component 3 is made of the 1st member 5 (chuck) and 2 the 2nd members 4,6 (member), and Fig. 2 has represented their sectional side view respectively.And Fig. 3 has represented the front elevation of the 2nd member 4 or 6, and Fig. 4 has represented the front elevation of the 1st member 5.
(c) and among Fig. 3, the 2nd member is made of left-side member 4 that clips the 1st member 5 and right side member 6 at Fig. 1, Fig. 2 (a).Because they are symmetrical shape, so explanation simultaneously.This left and right sides member 4,6 has and interts at the periphery of rotor 51, the inner peripheral surface 7 relative with it, is one on the circumference local C font annular element that cuts with otch 8.And, the 1st member 5 in the periphery side direction and be provided with depressed part the 9, the 2nd dip plane 10 and the 2nd in turn and draw in inclined-plane 11.And the end face of the 1st member 5 one sides is provided with the 2nd abutting part 12.
The lug boss 9a of end that depressed part 9 is set at a side opposite with the 2nd abutting part 12 of left and right sides member 4,6 is cut apart, with the lug boss 2a of shading ring 2 chimeric (with reference to Fig. 1).And, chimeric easy in order to make with shading ring 21, on lug boss 9a, be provided with conical surface 9b.And the 2nd dip plane 10 forms conical surface-shaped on left and right sides member 4,6, can combine like that with the 1st dip plane 16,17 of the 1st member 5 described later to be provided with sliding over each other.And the 2nd draws in inclined-plane 11 forms smooth bowl-shapely, can draw in inclined- plane 18,19 with the 1st of the 1st member 5 described later and combine like that with sliding over each other and be provided with.The 2nd draws in inclined-plane 11 forms along such direction: when the 2nd draw in inclined-plane 11 on one side and the 1st axis direction of drawing in inclined- plane 18,19 slip left and right sides member 4,6 one edge rotors 51 near the 1st member 5 when mobile like that, the 1st member 5 is pressed to the direction of the inboard radially of rotor 51, even the 1st member 5 leaves the direction of bobbin.At last, the 2nd abutting part 12 form can be with the 1st abutting part 20,21 butts of the 1st member 5 described later smooth bowl-shape.
These left and right sides member 4,6 usefulness polyacetal etc. and so on elastic restoring force is strong and thermoplastic resin easy moulding is one-body molded.That is, when pushing the 2nd dip plane 10, the narrow down diameter of inner peripheral surface 7 of the opening of otch 8 shrinks (along radially moving to the inside of rotor 51).And when not pushing the 2nd dip plane 10, the opening of otch 8 relies on elastic restoring force to get back to initial condition, gets back to the state of kink on rotor 51.
In Fig. 1, Fig. 2 (b) and Fig. 4, the 1st member 5 forms the C font annular element with otch 24 incisions in 1 place on the circumference.And, the 1st member 5 by the service portion of the two ends that are arranged on axis direction (left and right end portions), interior all sides of the central portion of axis direction be arranged to convex lug boss 23, with about lug boss 23 overlap joints of service portion and the central authorities part 22 of getting up constitute.About service portion on, the outer peripheral face 14,15 relative with the interior week of bobbin 52 forms the clamping surface that protrudes any than other outer peripheral face a little.When the diameter of the 1st member 5 was extended, promptly outer peripheral face 14,15 was when radial outside moves, and this outer peripheral face 14,15 is exerted pressure to the inner peripheral surface of bobbin 52, becomes the part on the inner peripheral surface that is pressed in bobbin 52.At left and right sides service portion, the 1st dip plane 16 and the 1st dip plane 17, right side on the left of the left and right end portions of interior all sides is formed with.And,, be formed with left side the 1st in the part near central authorities of interior all sides and draw in inclined-plane 18 and inclined-plane 19 is drawn on right side the 1st at left and right sides service portion.And, on lug boss 23, the 1st abutting part 20 and right side the 1st abutting part 21 on the left of the left and right end portions of interior all sides is formed with.
The 1st dip plane 16, left side is relative with the 2nd dip plane 10 of left-side member 4, and the 1st dip plane 17, right side is relative with the 2nd dip plane 10 of right side member 6, forms the smooth bowl-shape of combination respectively.And inclined-plane 18 and the 2nd of left-side member 4 are drawn in left side the 1st, and to draw in inclined-plane 11 relative, and inclined-plane 19 and the 2nd of right side member 6 are drawn in right side the 1st, and to draw in inclined-plane 11 relative, forms the conical surface-shaped of combination respectively.The 1st draws in inclined- plane 18,19 and forms along such direction about these: when their on one side and the 2nd axis direction mobile phase of drawing in inclined-plane 11 slip left and right sides members, 4,6 one edge rotors 51 to the 1st member 5 near the time, be subjected to the effect of left and right sides member 4,6, leave the direction of bobbin respectively.And left side the 1st abutting part 20 that is provided with on the lug boss 23 is relative with the 2nd abutting part 12 of left-side member 4, and right side the 1st abutting part 21 is relative with the 2nd abutting part 12 of right side member 6, and formation is similar to parallel face that can butt and is provided with in this wise respectively.And, bobbin 52 is being interted under the situation on the spool stand 50, for make left and right sides member 4,6 and chuck 5 when along axis direction near the time keep some gaps and butt not, the 1st abutting part 20,21 and the 2nd abutting part 12 separate certain clearance and are disposing.And, carry out under the situations such as pneumatics of confirming operation not interting bobbin 52, when making left and right sides member 4,6 and chuck 5 along axis direction when near each other, because mutual butt, chuck 5 is stuck in the left and right sides member 4,6, can controls the further hole enlargement action of chuck 5.
This chuck 5 is the same with left and right sides member 4,6, and is strong and thermoplastic resin easy moulding is one-body molded with polyacetal etc. and so on elastic restoring force.Therefore, when pushing the 1st dip plane 16,17, it is big that the opening of otch 24 becomes, the enlarged-diameter (along the side shifting radially outward of rotor 51) of chuck 5 (outer peripheral face 14,15).And when not pushing the 1st dip plane 16,17, the opening of otch 24 is because elastic restoring force is got back to initial condition.And, draw in inclined- plane 18,19 if push the 1st, then chuck 5 (outer peripheral face 14,15) is forced to undergauge.
Like this, near each other or become estranged by left and right sides member 4,6 and chuck 5 along the axis direction of rotor 51, this moment the 1st dip plane 16,17 and the 2nd dip plane 10 mutual actions, chuck 5 and left and right sides member 4,6 are exerted pressure for bobbin 52 and rotor 51 respectively or are removed and exert pressure, and clamping component 3 is for forcing or rely on the scalable structure freely of restoring force of self.So, when chuck 5 and left and right sides member 4,6 axis directions along rotor 51 are estranged from each other, draw in the mutual action that inclined- plane 18,19 is drawn on inclined-plane 11 and the 1st by the 2nd, the diameter of chuck 5 can be forced to dwindle.And the 2nd draws in inclined-plane 11 and the 1st draws in inclined- plane 18,19 and becomes chuck 5 is used the joint portion from drawing back of drawing back of bobbin 52.
And, on the outer peripheral face 14,15 of chuck 5, be formed with a plurality of V-slots 26 (with reference to Fig. 2 (b), Fig. 4) that prolong along axis direction.These V-slots 26 for discontinuous, remain in the circular arc thin groove like that on the outer peripheral face 14,15 owing to there are these grooves, it is sunken to form to bobbin 52 in pressure week, very little, further prevents skidding of circumferencial direction.
At last, as Fig. 1 and shown in Figure 5, for stride across except that the clamping component 3 that is configured in two ends, 2 bobbins 52 configurations adjacent with clamping component 3, shading ring 2 is for example aluminum products for having the annular element with the corresponding length of length of bobbin 52.By the two ends at this shading ring 2 above-mentioned lug boss 2a is set, this lug boss 2a is embedded in the depressed part 9 of member 4,6, and shading ring 2 is in the bonded assembly state with member 4,6.Thus, directly transmitted along the moving of axis direction of rotor 51 between all shading ring 2 and the member 4,6.
Constitute bobbin fixing device 1 as mentioned above like that.Next the action of this bobbin fixing device 1 is described with reference to Fig. 1 and Fig. 5.At first, the operation that is not inserted in the interspersed bobbin 52 of state on the spool stand 50 from bobbin 52 is described.At ordinary times, bobbin fixing device 1 is in clamped condition (state shown in Fig. 1 (b)).Promptly, discharge pressurized air from the pneumatics chamber 65 on spool stand 50 tops, lid member 59 since the effect of the elastic force of spring 64 be pressed along the direction of arrow a, each clamping component 3 is compressed along axis direction by shading ring 2, and the diameter of the chuck 5 of each clamping component 3 and left and right sides member 4,6 is expanded and compressed.In this state, pressurized air is imported pneumatics chamber 65.Thus, lid member 59 moves along the direction of arrow b, this motion is delivered to clamping component 3 and each shading ring 2, each clamping component 3 is expanded along axis direction, the diameter of the chuck 5 of each clamping component 3 and left and right sides member 4,6 shrinks respectively and expands, and bobbin fixing device 1 becomes the state shown in the state (Fig. 1 (a)) that does not clamp).Under this state, bobbin 52 interts in rotor 51 outsides of spool stand 50.Bobbin fixing device 1 still is in the state (not clamped condition) of release, forms the gap between the inner peripheral surface of outer peripheral face 14,15 and bobbin 52.
In this state, by discharging the pressurized air of pneumatics chamber 65, utilize the elastic restoring force of spring 64 to make and cover the pressuring direction (with reference to Fig. 5) of member 59 along arrow a.Thus, shown in arrow a among Fig. 1 (a) like that, between shading ring 2, produce the power of pushing direction.When this masterpiece time spent, chimeric by shading ring 2 and member 4,6, left and right sides member 4,6 relatively moves across the direction that the distance of chuck 5 between the axis direction upper edge is mutual narrows down.So, because the 1st dip plane 16,17 combines with the 2nd dip plane 10 of left and right sides member 4,6 about chuck 5, and the existence of the otch 8 of the otch 24 of chuck 5 and left and right sides member 4,6, the expanded in diameter of chuck 5, outer peripheral face 14,15 is pressed on the inner peripheral surface of bobbin 52, the diameter of left and right sides member 4,6 shrinks simultaneously, and inner peripheral surface 7 is pressed on the outer peripheral face of rotor 51.Its result, bobbin 52 is in by handle and is held in as the clamped condition shown in the Fig. 1 (b) on the rotor 51 of spool stand body.Therefore and owing to be formed with a plurality of thin triangular grooves 26 on the outer peripheral face 14,15 of chuck 5, the force of sliding friction with the circumferencial direction of bobbin 52 increases, and the turning force of rotor 51 can positively pass to bobbin 52.
With bobbin 52 be held in form sliver package P on the spool stand 50 after, need to discharge, extract the bobbin 52 of each sliver package P.At this moment, cover member 59 and overcome the pressuring direction (with reference to Fig. 5) of elastic force by once more pressurized air being imported in the pneumatics chamber 65, making along arrow b.Thus, as Fig. 1 (a) produce pulling force between the shading ring that is shown in 2 along arrow b direction.When this tension, because shading ring 2 and 4,6 chimeric connections of left and right sides member, left and right sides member 4,6 direction that each other distance enlarges in the axis direction upper edge relatively moves, and gets back to bobbin 52 and controls preceding initial position.Follow in this, the power of the direction of pushing mutually of effect is disengaged between the 1st dip plane 16,17 of the 2nd dip plane 10 of left and right sides member 4,6 and chuck 5.Therefore, be pressed in the state that the diameter of the chuck 5 on the inner peripheral surface of bobbin 52 is forced to expand and be eliminated, chuck 5 relies on the effect of self elastic restoring force to get back to initial condition.Simultaneously, because the 2nd the drawing in inclined-plane 11 and draw in inclined- plane 18,19 with the 1st of chuck 5 and combine of left and right sides member 4,6, chuck 5 is pulled to internal side diameter.That is, and the action of becoming estranged along axis direction between chuck 5 during bobbin 52 release movement and the member 4,6 links, and chuck 5 is pulled to internal side diameter.Therefore, when bobbin 52 release movement, the diameter of chuck 5 is retracted really and leaves bobbin 52, extracts bobbin 52 and becomes easy.In addition, because shading ring 2 is being connected at draw direction (arrow b direction) with clamping component 3, therefore guaranteed that 3 pairs of bobbins 52 of all clamping components are in release position.
And, in bobbin fixing device 1, under the state of extracting bobbin 52 (state of not inserting), carry out to the axis direction of clamping component 3 dwindle action the time, owing to the 2nd abutting part 12 butts of the 1st abutting part 20,21 of chuck 5 and left and right sides member 4,6, chuck 5 is stuck between the left and right sides member 4,6, therefore can prevent from too to enlarge and come off from left and right sides member 4,6 owing to chuck 5.
If adopt the bobbin fixing device 1 of above-mentioned explanation, because the chuck 5 when being provided with the release movement that is used to make chuck 5 and bobbin relatively moves with the axis direction of left and right sides member 4,6 and links, leave the joint portion 11,18 and 19 of bobbin 52, therefore, even deflation members such as rubber tape are not set, bobbin 52 is being discharged when extracting from spool stand 50, also can positively make clamping component 3 reduced, extract and become easy.Owing to do not need to tighten member, therefore can reduce the thickness t of the clamping component 3 shown in Fig. 1 (a).Therefore, the diameter that can suppress rotor 51 diminishes, and can prevent the terminal speed step-down, so can increase productivity.
In addition, the present invention is not limited to above-mentioned example, also can for example be out of shape enforcement as follows.
(1) though in this example, the 1st and the 2nd member constitutes the annular element of C type, so long as the member that can free constitute in diametric(al) scalablely, even with other the member of shape formation, also can obtain effect of the present invention.For example, the 1st and the 2nd member can be divided into a plurality of respectively in a circumferential direction.
(2) the 2nd member of shading ring and clamping component is also not necessarily leaveed no choice but constitute respectively, even make the member of the structure that they become one also can obtain effect of the present invention.
