Abstract
The utility model discloses a lower rib cover plate for automatic doffing. Through holes for bobbin gears to penetrate through are formed in a lower rib cover plate body, the bobbin gears fix hollow pipes or full-yarn bobbins through fixing devices on laying faces of the bobbin gears, and a hole is formed between every two adjacent through holes. Spinning stability is enhanced, production cost is reduced, and the operation process is simplified.
Description
Technical field
The utility model belongs to field of textiles, is specifically related to a kind of automatic doffing down rail cover plate.
Background technology
On external automatic doffing roving frame, during rove automatic doffing, the full yarn bobbin of rove having spinned is on down rail, whole down rail is pulled to outside machine, bobbin gear on it and the lift spindle vertical alignment doffing on lift spindle drive disk assembly, the lift spindle drive disk assembly that doffs starts descending, staggered interval half bare bobbin that plays doffs on lift spindle drive disk assembly, bare bobbin is aimed at the empty ingot of down rail place, and idle lift spindle is aimed at the full spool on down rail, when idle lift spindle inserts in full spool, tapered sleeve on lift spindle touches after spool mouth, lift spindle also needs to continue descending until tapered sleeve is triggered to the switch of lift spindle feet, thereby so that lift spindle feet opens the object that completes the full yarn of slinging.In this course of work, be that lift spindle continuation is descending until tapered sleeve is triggered to the process of the switch of lift spindle feet, doffing the bottom position of bare bobbin on lift spindle drive disk assembly must be lower than the bottom position of full spool, external automatic doffing roving frame in the past solves this problem with raising the table top of shelving spool on bobbin gear conjunction, its shortcoming is 1, has improved the center of gravity of textile tubes, the stability of spool while having weakened spinning.2, because will raise the table top of shelving spool on bobbin gear conjunction, so virtually increased manufacturing cost.3, the space between down rail in increase, upwards raises complete machine, is not easy to operative employee's operation, and after machine, raising of guide strip rack also makes the meet accident probability of drawing-off of sliver increase.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, and a kind of automatic doffing down rail cover plate is provided.
Technical scheme: in order to achieve the above object, the utility model is specifically achieved like this: a kind of automatic doffing down rail cover plate, on described down rail cover plate plate body, have the through hole that bobbin gear is passed, bobbin gear is shelved fixture on face fixedly blank pipe or full yarn bobbin by it, between described adjacent two through holes, offers a hole.
Wherein, described fixture is spindle blade.
Wherein, described hole is through hole, and this through-hole diameter is greater than the maximum gauge of blank pipe or full yarn bobbin bottom.
Wherein, described hole is spill counterbore, and this spill counter bore hole diameters is greater than the maximum gauge of blank pipe or full yarn bobbin bottom, and bottom blank pipe or full yarn bobbin and spill counterbore, has gap when blank pipe or full yarn bobbin drop to extreme lower position.
Beneficial effect: place, the utility model empty ingot position that bare bobbin is aimed on down rail cover plate is provided with a hole, to guarantee that bare bobbin needs to continue descending needed space in this course, make the bottom of bare bobbin lower than the plane of down rail cover plate, need not improve the table top of shelving spool on bobbin gear conjunction, strengthened the stability of spinning, reduce production cost, simplified operating process.

Fig. 3 is the utility model work schematic diagram.
The specific embodiment
As shown in Fig. 1～2, the disclosed a kind of automatic doffing down rail cover plate of the utility model, on described down rail cover plate 1 plate body, have the through hole 3 that bobbin gear 2 is passed, bobbin gear 2 is shelved fixture 4 on face fixedly blank pipe 6 or full yarn bobbin 7 by it, this fixture 4 is spindle blade, between described adjacent two through holes 3, offer a hole 5, this hole 5 is spill counterbore, this spill counter bore hole diameters is greater than the maximum gauge of blank pipe 6 or full yarn bobbin 7 bottoms, and there is gap with spill counterbore bottom in blank pipe 6 or full yarn bobbin 7 when blank pipe 6 or full yarn bobbin 7 drop to extreme lower position.
As shown in Figure 3, the utility model is specifically worked like this: before Speed frames automatic doffing, and staggered half bare bobbin 6 and one lift spindle 9 in midair that is being spaced on the lift spindle drive disk assembly 8 that doffs; Whole down rail is pulled to outside machine together with down rail cover plate 1, and now completely yarn bobbin 7 is placed in shelving on face on bobbin gear 2, vertically aims at the empty lift spindle 9 doffing on lift spindle drive disk assembly 8, and hole 5 is vertically aimed at the blank pipe 6 doffing on lift spindle drive disk assembly 8.While doffing, the lift spindle drive disk assembly 8 that doffs comes downwards to sky lift spindle 9 and inserts in full spool 7, when frustum contacts the mouth of pipe of full spool 7, blank pipe 6 starts to enter in described hole 5, continue descending, until described tapered sleeve triggers the moment of feet switch, feet is opened, for the full yarn bobbin 7 of slinging, get ready, meanwhile, the blank pipe 6 doffing on lift spindle drive disk assembly 8 comes downwards to lowest part; Then, the lift spindle drive disk assembly 8 of doffing rises, and staggered on the lift spindle drive disk assembly 8 that now doffs what be spaced is half bare bobbin 6 and half full spool 7; When rising to full spool 7 and thrown off the constraint (as spindle blade) of fixture 4, the lift spindle drive disk assembly 8 that doffs stops rising, the distance of all half ingot distances of lift spindle transverse shifting, make bobbin gear on down rail cover plate 12 aim at the bare bobbin 7 doffing on lift spindle drive disk assembly 8, the hole 5 perpendicular alignmnets full spool 7 on lift spindle drive disk assembly 8 that doffs; The lift spindle drive disk assembly 8 that doffs is again descending, until the bottom surface of bare bobbin 6 is placed on shelving on face on bobbin gear 2, now described full spool 7 starts to enter in described hole 5, continue descending, until the moment that on the lift spindle of lifting bare bobbin 6, tapered sleeve triggers feet switch is regained feet, for discharging bare bobbin 6, get ready, meanwhile, the full spool 7 doffing on lift spindle drive disk assembly 8 comes downwards to lowest part; The lift spindle drive disk assembly 8 that doffs rises again, and staggered on the lift spindle drive disk assembly 8 that now doffs what be spaced is lift spindle 9 and half full spool 7 in midair; And bobbin gear 2 on down rail cover plate 1 to shelve what on face, place be bare bobbin 6.The lift spindle drive disk assembly 8 that doffs rises to highest order, prepare the exchange operation of next step empty full packages, and down rail is retracted in machine together with down rail cover plate 1, prepares the rove spinning of next round, forms new full spool.
