When the package 45 that is gone out certain spinning unit 2 by the graphic sensor of omission became full volume, cell controller stopped spinning apparatus 9, and the chassis 4 that will doff is transferred to this spinning unit 2.Almost meanwhile, cell controller makes the package 45 of full volume leave package drum 74 thus, thereby does not make propulsive effort be delivered to this package 45 through the reel cage arm 71 in the wind2 13 is rotated to the left side of Fig. 2 (face side of spinning unit 2).Even after leaving package drum 74, the inertia rotation is also carried out in package 45.
When doffer 60 arrives spinning unit 2 according to the scheduling of cell controller, rotate to the top through making swivel arm 63, the leading section that makes guide portion 61 thus is near package 45.Doffer 60 guides compressed-air supply with cylinder 62 to bobbin under this state, makes the bobbin guiding with cylinder 62 elongations, thereby makes support unit 60 rotate and contact with the side face of package 45 to the top.Thus, doffer 60 can utilize the surface of 65 pairs of packages 45 of support unit to carry out friction braking, thereby can make the inertia rotation of package 45 stop (with reference to Fig. 5).Even doffer 60 constitutes after the rotation of package 45 stops fully, also keep making support unit 65 and package 45 state of contact.In following explanation, the position of this package 45 of support unit 65 when reel cage 70 is accepted package 45 is called " primary importance ".
At this moment, support unit 65 continues and package 45 state of contact as stated.Therefore, package 45 can not fallen on the support unit 65 or directly fall on the rake 81 and impacted.As stated; Through select to use the support unit 65 of suitable shape according to the shape of package 45; Thus doffer 60 can make support unit 65 with respect to package 45 with large tracts of land contact, thereby can stably support (guiding) package 45 and not produce it is rocked.
As stated, in the moments that package 45 and rake 81 contact at first, support the part of the weight of these packages 45 by support unit 65, remaining weight is born by rake 81 (portion 84 is accepted in package).Like this, because package 45 is in the moment that arrives rake 81, support unit 65 supports the weight of this package 45 reliably, so doffer 60 becomes the formation that the quality that is difficult to cause package 45 reduces.
In this embodiment, package 45 and this package 45 after rake 81 contacts arrive carry put portion 82 before, also by the part of the weight of guide portion 61 (support unit 65) supporting package 45.Therefore; Even for example from the viewpoint of spinning frame 1 miniaturization and have to make under the situation that the angle of rake 81 becomes precipitous; Doffer 60 also can be controlled with the strong excessively mode of the rolling impetus that does not make package 45 on one side, carries the portion 82 of putting Yi Bian package 45 is moved to.In addition, along rake 81 guiding packages 45 time, roller member 67 contacts with rake 81, and this roller member 67 is rotated with the mode of on rake 81, rolling, and guide portion 61 is moved reposefully.
In addition, temporarily under free rolling situation on the rake 81, the road yarn of advancing of package 45 is not straight yarn as stated, draws the bent yarn of turning to the path side and become in the package 45 of conical by its shape (coniform).But, in this embodiment, can limit the axial both ends of the surface of package 45 on one side through limiting part 66, on one side along rake 81 these packages 45 of guiding, even therefore the package 45 of conical by its shape also can straightly be rolled towards carrying the portion of putting 82.
In addition, doffer 60 also carries out bobbin operation is set in this doffing operation.Promptly, when when bobbin support 72 takes off package 45, reel cage arm 71 is become under the state of rotation, the position (with reference to the empty yarn of Fig. 6) that reel cage motion arm 89 is moved to can operate reel cage 70 with the mode near coiling drum 74.Before reel cage motion arm 89 carried out the supply of bobbin 48, operation reel cage arm 71 was so that a bobbin support 72 leaves another bobbin support 72.
