Supporting member 65, limiting part 66 and roller member 67 are provided with installing plate 68.
Supporting member 65 is created as flat part, and has been arranged side-by-side two.Each supporting member 65 with across The mode of a pair of installing plate 68 configures.The contact surface (bearing-surface) being formed by two supporting members 65 is as shown in figure 3, be formed as it The relatively shallowly recessed V-shaped of middle body.
Supporting member 65 is made to rotate upward together with installing plate 68 by extending bobbin guiding cylinder 62, thus Supporting member 65 can be contacted with the package 45 in the state of being kept by coil holder 72.Thus enable that the above-mentioned of this package 45 Inertial rotation stops.Package 45 can be drawn by supporting member 65 while supporting the weight of the package 45 accepting from reel cage 70 Lead rake 81.And then, supporting member 65 also can be contacted with this package 45 after package 45 is contacted with rake 81, thus Package 45 can be directed to mounting portion 82 along rake 81.
As shown in Fig. 4 (a), supporting member 65 by the contact site 65a that can be contacted with the outer peripheral face of package 45 and is installed on Installation portion 65b and 65c of installing plate 68 is constituted.In addition, Fig. 4 (a) is to observe two supporting members from this coiler device side 13 The figure of the supporting member 65 being configured at coiler device 13 side in 65.
In order to suitably carry out stopping the rotation of package 45 and the guiding of package 45, need to make supporting member and package 45 Uniformly contact.That is, if supporting member 65 acts on the power of package 45 and there is deviation, can be to a part for package 45 Act on larger load, thus this package 45 can damage sometimes.Therefore, when winding the package 45 of conical by its shape, such as Fig. 4 (a) Shown, using the skewed supporting member 65 that have adjusted after the length of installation portion 65b and 65c mating with this conical by its shape. In the package 45 of wind parallel shape, such as shown in Fig. 4 (b), using the structure of installation portion 65b and the equal length of installation portion 65c The horizontal supporting member 65 becoming.
Fig. 4 (a) and the supporting member 65 shown in Fig. 4 (b) just can be from installations by taking off fixed component (such as bolt) Plate 68 simply takes off.Therefore, even if it is also possible to only logical in the case of changing the shape of package 45 being formed by spinning frame 1 Cross replacing supporting member 65, doffer 60 just copes with the doffing operation of the package 45 changing shape.
Limiting part 66 is formed as tabular, and is installed on installing plate 68 with the substantially vertical state erecting.Limiting unit Part 66 has been arranged side-by-side two pieces substantially in parallel, can limit the position of the axial direction of package 45 from reel cage 70 acceptance from both sides. Thus, prevent the package 45 receiving from falling from contact site 65a.
Roller member 67 can rotatably be supported on installing plate 68.Roller member 67 is configured to when guide portion 61 is along rake 81 During guiding package 45, can rotate on this rake 81.According to this composition, doffer 60 can swimmingly carry out package 45 Guiding, and be prevented from the abrasion of guide portion 61 and rake 81 etc..In addition, the guide portion 61 of present embodiment is to possess The composition of three groups of (total 6) roller members 67.
Next, flow process doffer 60 being carried out when doffing operation and bobbin setting operation with reference to Fig. 5 and Fig. 6 is carried out Explanation.Fig. 5 is the longitudinal section of state when representing that guide portion 61 makes the inertial rotation of package 45 stop.Fig. 6 is that explanation is doffed The longitudinal section of operation.In addition, in the present embodiment, doffing operation and bobbin setting operation are carried out simultaneously in parallel.
When the package 45 that the sensor being illustrated by omission detects certain spinning unit 2 becomes full volume, cell controller makes Spinning apparatus 9 stop, and this spinning unit 2 is transferred to by the chassis 4 that will doff.Almost meanwhile, cell controller passes through to roll up Reel cage arm 71 in winding apparatus 13 rotates to the left side (face side of spinning unit 2) of Fig. 2, so that the package 45 of full volume is left Package drum 74, thus do not make driving force be delivered to this package 45.Even if after leaving package drum 74, package 45 is also carried out inertia rotation Turn.
When doffer 60 reaches spinning unit 2 according to the scheduling of cell controller, by making cursor 63 upwards Side rotates, and the leading section thus making guide portion 61 is close to package 45.Doffer 60 supplies compressed air in this condition Bobbin guiding use cylinder 62, so that bobbin guiding cylinder 62 is extended so that supporting member 60 rotate upward and with package 45 Circumferential contact.Thus, doffer 60 can carry out frictional damping using supporting member 65 to the surface of package 45, so as to The inertial rotation enough making package 45 stops (with reference to Fig. 5).Even if doffer 60 be configured to package 45 rotation stop completely after, Also keep the state making supporting member 65 contact with package 45.In the following description, supporting member 65 is accepted from reel cage 70 The position of this package 45 during package 45 is referred to as " primary importance ".
Doffer 60, before the inertial rotation of package 45 stops completely, makes reel cage motion arm 89 move to shown in Fig. 5 Position (position that reel cage is operable to).When package 45 stops completely, then doffer 60 pass through reel cage motion arm 89 with The mode that a coil holder 72 leaves another coil holder 72 is made to operate reel cage arm 71, by the package 45 of full volume from reel cage 70 Take off.
Now, the state that supporting member 65 continuation as described above is contacted with package 45.Therefore, package 45 will not fall supporting On part 65 or fall directly on rake 81 and impacted.As described above, selecting to make by the shape according to package 45 With the supporting member 65 of suitable shape, supporting member 65 can be made to connect with large area with respect to package 45 by this doffer 60 Touch such that it is able to stably supporting (guiding) package 45 and not producing and so that it is rocked.
Doffer 60 passes through to weaken the pressure being supplied to bobbin guiding cylinder 62 it becomes possible to support on one side expiring of taking off The weight of the package 45 of volume, makes supporting member 65 rotate downwards.When supporting member 65 rotates downwards and according to need When cursor 63 to be made rotates downwards, package 45 horse back contacts (reference with rake 81 (package receiving portion 84, the second position) Fig. 6).So, doffer 60 is in the state of package 45 is supported by part 65 supporting, by this package 45 from primary importance to the Two position conveyings.
As described above, the moment initially contacting with rake 81 in package 45, this package 45 is supported by supporting member 65 A part for weight, remaining weight is born by rake 81 (package receiving portion 84).So, because package 45 reaches The moment in portion 81, supporting member 65 reliably supports the weight of this package 45, and therefore doffer 60 becomes and is difficult to cause package The composition that 45 quality reduces.
