The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2: the present invention is mainly used in spindle 10 and spool 11 is on the fine spining machine of friction driving type.Described device for previously withdrawing bobbins is mainly coiled on 6 by doff dolly 2 and the pre-pine of the conical surface mounted thereto to be formed; The dolly 2 that doffs is placed on the guide rail 1 and can walks along guide rail 1, and the dolly 2 track route A that doff are parallel to fine spining machine spindle 10 line of centres B; Side near spindle 10 on the described dolly 2 that doffs utilizes bolting that installing rack 3 is arranged, and vertically is fixed with rotating shaft 4 on installing rack 3, and rotating shaft 4 is tightened fixing by the bolt of its lower end; The pre-pine dish of the described conical surface 6 is installed in the rotating shaft 4 by bearing 5, the dish plane of the pre-pine dish 6 of this conical surface is perpendicular to the length direction of spindle 10, the edge of the pre-pine dish 6 of the conical surface is made as the conical surface, evenly offer at least three arc notch 15 around the edge of the pre-pine dish 6 of the conical surface, arc notch 15 in the present embodiment preferably is set to 8, the spacing of adjacent arcs v notch v 15 equates that with the spacing of adjacent spindle 10 arc notch 15 radiuses are greater than spindle 10 radiuses and less than spool 11 bottom surface radiuses.
In concrete the application, when the dolly 2 that doffs is installed, one of them arc notch 15 that the pre-pine dish 6 of the conical surface at first is set embeds between first spindle 10 and spool 11 bottom surfaces, doff dolly 2 along track route A walking (direction of travel is shown in arrow among the figure) work of doffing, arc notch 15 on the pre-pine dish 6 of the conical surface is subjected to stopping of first spindle 10 and is forced to revolution (gyratory directions is shown in arrow among the figure), arc notch 15 on it embeds successively and withdraws between each spindle 10 and spool 11 bottom surfaces, the conical surface of the pre-pine dish of the conical surface 6 peripheries contacts with spool 11 bottom surfaces successively, the pre-pine dish of the conical surface 6 conical surfaces and contact-making surface between spool 11 bottom surfaces be one along the surperficial spiralling curvilinear plane of spindle blade, walking along with the dolly 2 that doffs, the pre-pine dish of the conical surface 6 conical surfaces compressing spool 11 bottom surfaces, spool 11 is lifted, thereby realize pre-tube drawing operation.
As shown in Figure 1, because spindle 10 general elastic spindles that adopt commonly used on the existing fine spining machine, promptly the load-carrying construction 14 of spindle 10 is the elastic floating load-carrying construction, and spindle 10 has the interval of fluctuating at its axial location, between this floating zone generally at 3～4mm; The detent mechanism that keeps sustained heights for the wharve 12 that guarantees the action of pre-tube drawing accurately and reliably, preferably be provided with on the described device for previously withdrawing bobbins to be used to make spindle 10.Described detent mechanism is mainly by pressing plate 8 with argue for the sake of arguing and 9 forms, and pressing plate 8 is fixed on the side stand 7 by screw, and side stand 7 is installed on the installing rack 3, the arc limit of the bottom of pressing plate 8 for bending down; Argue for the sake of arguing and 9 utilize the little axle pass its middle part to be installed on the bolster 13 of spindle 10, argue for the sake of arguing and 9 can rotate around little axle, 9 one ends of arguing for the sake of arguing withstand on wharve 12 bottom surfaces of spindle 10, and 9 other ends of arguing for the sake of arguing are positioned on the course of pressing plate 8.
In concrete the application, doff dolly 2 along track route A walking (direction of travel is shown in arrow among the figure) work of doffing, when the dolly 2 that doffs runs to the position of spindle 10,9 stressed the pressing down of an end that contact with pressing plate 8 of arguing for the sake of arguing, argue for the sake of arguing 9 around little axle rotation, 9 other ends of arguing for the sake of arguing lift and push wharve 12, and the arc notch 15 on the pre-pine dish 6 of the conical surface embeds under spool 11 bottom surfaces simultaneously.This detent mechanism has effectively been eliminated between above-mentioned floating zone, makes the wharve 12 of spindle 10 remain sustained height, guarantees reliable contact of the pre-pine dish of the conical surface 6 conical surfaces and spool 11 bottom surfaces.
As shown in Figure 1, because the spacing of the spindle 10 of different size fine spining machine has nothing in common with each other, the pre-pine dish 6 of the conical surface among the present invention preferably is made up of master body 6a and conical surface annular disk 6b, and master body 6a center is provided with a boss, and conical surface annular disk 6b is enclosed within on this boss and adopts screw-driving to fix.Described conical surface annular disk 6b can be convenient for changing as the case may be, has improved the scope of application of the present invention greatly.
