Abstract

Sliver (F) is supplied from a number of sources to a drafting system (5, 6) over a guiding arrangement (14) which turns the sliver into a direction (T) perpendicular to the axes of the drafting system inlet rollers. Several guides (16a-16f) are arranged across the width (B1) of the drafting system (5, 6) to guide each sliver (F) individually from an upward into a horizontal feed direction (T).

Description

Sliver feeding apparatus

The present invention relates to a kind of the many slivers of supplying with the position from difference are sent to the right feed unit of drafting system import roller, level and realize turning to substantially in this feed unit with the sliver of the perpendicular supply of drafting system direction of transfer, and transmit along the direction perpendicular to drafting system import roller countershaft.

For to the sliver processing machine,, one group of sliver fed separately be positioned at the feed unit that lapper is given cotton platform top for example to the lapper feeding.Usually, two to three such drafting systems are arranged in one by one to cotton platform top.These single slivers are extracted out through the roller of bar tube top from the bar tube, are sent to drafting system separately.These tubes in a row are arranged on to by the cotton platform, that is to say, sliver is perpendicular to giving vertically feeding of cotton platform.

A kind of like this feed unit is described in the specification brochure (printing and publishing in September, 1991) of " Cherry-Superlap-Sl 100 " of Hara Shokki company.Here, give that cotton platform is other to have three groups respectively with the bar tube group of 12 bar tubes.That is to say, feed 12 slivers to each drafting system and form cotton sheet that the drawing rollers lateral alignment in the drafting system is given the direction of transfer of cotton platform.In order regularly to feed these single slivers in the drafting system separately, these slivers of supplying with the position from the bar tube turn to downwards through the guiding roller and deliver to that to transmit roller right.To being arranged before, an additional interval keeper guides sliver at separately transmission roller from the side.These pass the turning member on the sliver arrival guide plate that transmits the roller nip gap, and the sliver level turns to 90 ° there, feeds drafting system again.

Sliver turned to for cotton platform zone three times before regularly feeding drafting system side by side altogether in this feed unit.From technical standpoint, turn to have a negative impact to the sliver structure at every turn.May be distorted at the steering position sliver, this can play negative consequence to drafting process subsequently.

Therefore, task of the present invention is to reduce the quantity of sliver steering position, and a kind of simple and low sliver feeding apparatus of cost is provided.

This task is to solve like this, and feed unit is made up of a plurality of guiding partss, and they are dispersed in the width range of drafting system, are used for making each root sliver to turn to respectively and the perpendicular direction of transfer of the horizontal direction of the supply downwards.By means of this layout and the structure of feed unit, might be as long as a steering position just can be fed drafting system with sliver.

Advise that this guiding parts is made of rotational symmetric turning member.

Turn to and improve guiding for fear of additional sliver, suggestion is perpendicular with the sliver direction of the supply with the rotation axes of symmetry of supplying with the corresponding guiding parts in position (from supplying with the position).

In order to make guiding parts aim at corresponding supply position better and towards the position of feeding of drafting system, the suggestion guiding parts supports like this, the residing vertical plane of axle of guiding parts is partly intersected.So might make each guiding parts indivedual positions of feeding of aiming at its supply position and drafting system on its position, guarantee that sliver turns to smoothly.

In addition, by means of this, might make from each sliver of supplying with the position to become star to feed.That is to say, turn to the sliver guider that no longer needs other to assist between the roller accordingly in sliver supply position and its.

Advise a kind of like this structure, wherein the axle of guiding parts and they be arranged on one with the perpendicular plane of the downward transport direction of transfer member in.Adopt this layout can obtain a clearly sliver steering position, allow sliver to finish without difficulty and connect with in place.

Further suggestion is that the axle grouping of guiding parts is arranged on the different horizontal planes, forms a kind of steering position design of compactness, in this design, can avoid sliver to intersect and sliver between interference, and can bestly aim at the position of feeding of drafting system.

If advise that further guiding parts supports like this, the part of their axle is tilted by different way with respect to horizontal plane, then simplified guiding parts and fed the accurate of position and aim at above-mentioned.

In order will to feed to drafting system from the sliver of both sides, suggestion divides the plane to become the setting of mirror image ground with respect to the vertical centering control of drafting system guiding parts.

Preferably guiding parts is arranged on a plane domain that the branch plane outwards becomes fir shape (umbrella) to extend from drafting system.

Reduce to minimum in order to make between guiding parts and the sliver in the friction of steering position, the suggestion guiding parts adopts the roller that turns to of rotatable support.For sliver is accurately led, this turns to and is provided with one or more sliver gathering sills on the roller.If one turns to roller simultaneously many slivers to be turned to, suggestion is provided with a plurality of sliver gathering sills.So just sliver as much as possible regularly might be fed drafting system.

Become a cotton sheet that provides to drafting system in order to make from the sliver that turns to roller, further suggestion is provided with one below the roller and has and arrange the sliver parts of sliver mechanism at interval turning to, and there sliver parts extend along the width of drafting system.

Sliver mechanism can be made of hole adjacent one another are and that be staggeredly arranged.This hole has corresponding chamfering in the sliver inlet region.

Yet also may design the hole like this, lay the guide thimble of guiding sliver with it.That is to say that these sleeve pipes can be loaded onto or pull down individually.So just might make a kind of sliver parts of making by high-abrasive material especially.Preferably guide thimble is made of pottery.

In order when sliver is placed to the sliver parts, to be easier to connect sliver, on the suggestion sliver parts side to be set and to open wide the slotted eye that has different length.

Aligned with each other in order to make from the sliver of sliver parts, the sliver mechanism of suggestion sliver parts by fix with adjustable way, adjacent interlaced arrangement, the guide thimble that has a through hole constitute.

Preferably guide thimble is bearing on the fastening pole in the mode that middle minute plane with respect to drafting system can be displaced sideways.

This fastening pole can be made of a bar or a bearing support that has pod, and guide thimble is adjacent one another are, supporting is thereon in a movable manner.Realize being fixed in a position with screw there.

In order when guiding sliver sliver not to be rubbed each other before the sliver parts, suggestion is provided with two fastening poles that are arranged in juxtaposition at least, and every fastening pole going up is installed one group of guide thimble adjacent one another are.

Every group of guide thimble answered the obliquity of symmetry axis should help that sliver is pooled cotton sheet and is delivered to subsequently drafting system.

Suggestion becomes to shrink shape with the via design of guide thimble, and this will make connecting than being easier to of sliver.

In the version of further suggestion, from the sliver direction of transfer, guide thimble is provided with at first the through hole that shrinks, spreads then.So, make good connecting become possibility on the one hand, might realize the automatically cleaning of through hole on the other hand, that is to say the contamination that reduces through hole.

In order to improve the service life of guide thimble, advise that this sleeve portion ground is made of pottery or sintered aluminium.

In order to make the inlet of from the sliver of sliver parts, especially aiming at drafting system preferably, advise that fastening pole fixes in the mode that can make lateral adjustment with respect to branch plane in the drafting system at cotton sheet side portion potential energy.One group of guide thimble is displaced sideways in a direction simultaneously.

Best, the supply position of sliver is made of the roller that is rotatably supported on the cradle, and the turning cylinder of roller is arranged like this, makes it be in substantially parallel relationship to each corresponding axle that turns to roller.

As the auxiliary member of feeding of drafting system, after the sliver parts followed by guiding roller and a guide plate, so that cotton sheet is delivered to first jaw position of drafting system.

Further suggestion is that these sliver parts are a roller that has each sliver of a plurality of confessions with gathering sill.

Figure 16 is the schematic side view of a kind of possibility embodiment of guide thimble among Figure 13.

Fig. 1 illustrates a kind of lapper 1 that forms lap 2, and this lap 2 then is sent to combing machine and does further processing.Be provided with one on this lapper 1 and give cotton platform 4, two drafting systems 5 and 6 have been installed for cotton platform top.From bar tube group R ₁To R ₄In bar tube K feed this two drafting systems 5,6 through the corresponding sliver F that supplies with position 8 and extract out.These tube groups R ₁-R ₄Be arranged in both sides to cotton platform 4.These are supplied with position 8 and can constitute by sending roller 9 as shown in Figure 5.These are sent roller 9 and are supporting in the mode of freely rotating around axle 10.Sending roller 9 is rotatably mounted on the cradle 12.The sliver F that extracts out from bar tube K is sent to feed unit 14, and sliver F redirect to vertical direction from the position of an approximate horizontal on this feeds to position 14.The details of this feed unit form with enlarged drawing in Fig. 3 and Fig. 4 shows.

Feed unit 14 is made of a plurality of roller 16a to 16f that turn to, and their groupings are arranged on the different horizontal plane I-III in rotating mode.These turn to roller 16a to 16f to be rotatably supported on the bearing support 18, and on the bar 20 of the bearing support 18 fixing frames of not describing in detail in the drawings.This bearing support 18 hangs on the bar 20 in a movable manner, and is locked in selected position by screw 21.These turn to a roller axle 17a to 17f separately to be positioned at one and see it is the zone of plane inclined 23 or 24 from vertical direction.

They are to arrange like this, make to turn to roller 16a to 16c and become the mirror image setting with respect to turning to roller 16d to 16f, arrange thereby turn to roller to form a kind of fir shape (being umbrella).

As appreciable by Fig. 3, axle 17a to 17c place Plane intersects.Because an axle 17a to 17f has different angles, thereby might make sliver F directly be transported to feed unit 14 and no longer include other special steering position by separately the roller 9 of sending.Turning to respectively has two sliver gathering

sills

47,48 on each among the roller 16a to 16f, hold a sliver separately.To this,, turn to the axle 17c and axle 10 almost parallels of sending roller 9 accordingly of roller 16c as Fig. 5 specifically noted.From sending roller 9 to the path that turns to roller 16c, this sliver is supported by the cross bar 26 that is arranged on the cradle 12 in vertical direction at sliver F.Special arrangement by this roller 16a to 16f that has described just might make these send through the sliver that turns to roller to change feeding direction downwards, thereby they are sent with cotton sheet 30 forms with respective width B, and this width B will be adapted to the needs of drafting system 5 thereafter or 6.For make these slivers F in this width B each other respective aligned be sent to drafting system 5 or 6, sliver parts 15 that have a plurality of holes 28 are set below feed unit, the quantity in these holes 28 is corresponding with the quantity of the sliver F that transmits downwards.

As ise apparent from FIG. 3, the configuration of staggering of these holes 28 along continuous straight runs in sliver parts 15.Determined the structure of cotton sheet 30 thus, this structure is decided by the passage that sliver passes sliver parts 15.There is chamfering 29 in these holes 28 in the sliver porch.This can make connecting than being easier to of sliver on the one hand, prevents to damage the outer fiber of sliver on the other hand.A kind of like this chamfering 29 can also be arranged in the outlet of these sliver parts 15.

Fig. 7 provides a kind of particular embodiment of these sliver parts 15, wherein, a ceramic chamber lining 32 has been installed in hole 28, has a through hole 33 that supplies sliver F to pass on lining 32.The embodiment of Fig. 7 is compared with Fig. 4 embodiment, and hole 28 has a bigger diameter, and through hole 33 is corresponding to the diameter of Fig. 4 embodiment mesopore 28.The variation of this embodiment shown in Figure 7 can make the manufacturing of sliver parts 15 become simply on the one hand, on the other hand can be when lining 32 wearing and tearing resleeve more.The material of lining 32 and shape can be complementary with the quantity and the material of sliver.

Fig. 8 provides the another kind of embodiment of these sliver parts 15, and the strip shape slotted

eye

35 and 36 that its mesopore 28 is opened wide by a side replaces.Strip shape slotted eye 35 is different with 26 length, thereby can keep the structure of sending in Fig. 3 and Fig. 4 embodiment.The embodiment of Fig. 8 brings special advantage, and sliver is easy to connect, and that is to say sliver to be pointed for connecting.

As seen from Figure 6, the cotton sheet of sending downwards 30 arrives the guiding roller 38 that is supporting with free rotating manner.Guiding roller 38 is arranged on the top of guide plate 39, and cotton sheet is delivered to the import roller of drafting system 5 to 41 through guide plate 39.Cotton sheet 30 drawing-off or stretching in drafting system 5, and under the jaw line that drives delivery roller 45, arrive through guide surface 44 as cotton sheet 43 and to give cotton platform 4.The cotton sheet of being sent by drafting system 6 42 with cotton sheet 43 and close, then is sent to rolling mechanism in this jaw zone.Guiding roller 38 is set directly on the guide plate 39, forms the jaw that is transmitted cotton sheet with guide plate 39.That is to say, no longer can free deflection at this jaw district sliver, especially sliver here no longer may be twisted and form and not wish the structure that occurs.

Yet such imagination, feed unit 14 are in tilted layout in vertical direction, thus by guiding roller 38 do assisted diversion just become unnecessary.

Fig. 9 illustrates the another kind of embodiment of lapper 1, and its parts are consistent with the parts of Fig. 1 embodiment basically.The feed unit 14 that only constitutes sliver F turning member is different with Fig. 1 embodiment.Especially from the partial enlarged view of Figure 10 side view and Figure 11 and 12 this repugnancy as can be seen.

Sliver is from bar tube group R ₁To R ₂And R ₃To R ₄In bar tube K be sent to the feed unit 14 that is horizontal substantially separately.

Sliver F arrives the associated roller 55a to 55o (Figure 12) that turns to through bar tube K supply position 8 separately.

Turn to roller 55a to 55o to be rotatably supported in staggered connecting plate 53a to 53o.Connecting plate 53a to 53o is fixed on bearing support 50 or the bearing support 51 in a certain distance apart from one another.

Bearing support

50,51 is installed on the bar 52, becomes the α angle with the vertical centering control branch plane M of feed unit 14 separately.As what can find out especially from Figure 11 side view, bearing

support

50,51 and turn to roller 55a to 55o to be in substantially in the horizontal plane.For vividerization ground explanation this point, drawn horizontal plane H and each turn to the line A of roller shaft ₁And A ₂Can find out line A thus ₁And A ₂Be parallel to horizontal plane H substantially.

Among each 56a to 56o except two exceptions all with angle beta of horizontal plane H inclination.Axle 56b and 56i parallel with horizontal plane H.With respect to the position, angle of horizontal plane H is to constitute like this, make the roller direction in hole 28 on the sliver parts subsequently that turns to separately transmit sliver F, thereby sliver F no longer produces additional turning to.That is to say that each sliver F does not produce other stress turning to roller 55a to 55o place to turn to smoothly.This point is also by means of the line A of axle 56a to 56g with respect to axle ₁And axle 56h to 56o is with respect to the line A of axle ₂Another kind of obliquity reach.Just might make each rotating shaft that turns to roller be parallel to the rotating shaft 10 that associated tube K place sends roller 9 substantially thus as shown in Figure 5.

In addition, this embodiment that is positioned at a cardinal principle horizontal plane H, becomes fir shape (umbrella) to arrange of feed unit forms a kind of steering position that is easy to operate.That is to say, be easy to find out that each turns to the associated matching relationship of sending roller 9 of roller.Feed unit 14 is fixed on the frame (not drawing among the figure) through bar 52.This fixing can constitute like this, makes the variation of feed unit 14 energy realization levels and/or upright position.

In example shown in Figure 12, turning to does not have sliver F on roller 55g and the 55o, and these two rollers can be used for holding standby sliver (not drawing among the figure), perhaps as bar tube group R ₁To R ₄In a sliver F is arranged separately in addition, hold this root sliver F when from its 7th bar tube K, sending.

Can also imagine, adopt fixing turning member, for example replace the roller 16a to 16f and the 55a to 55o of rotatable support with rotational symmetric ceramic member.Though this can produce bigger friction at the steering position place with respect to turning to of rotatable support roller, yet this steering component manufacturing is simple, low price.

Turn to roller to obtain position, corresponding angle at its horizontal plane and vertical plane in order to make, connecting plate 53a to 53o must corresponding interlaced arrangement (as shown in the figure) in the solution of Figure 11.

Sliver is similar to the described embodiment of Fig. 6 through the drafting system 5,6 that sliver parts 15 continue to be sent to separately in the embodiment of Figure 12.

Figure 13 and Figure 14 have provided the another kind of particular embodiment of sliver parts 15.

Here, adopt arrangement adjacent one another are, removable guide sleeve pipe 58 and 59 to replace being arranged on simple through hole 28 on the sliver parts 15.Offer funnel-shaped hole long narrow, that shrink on the guide thimble 58,59 downwards.The shape of this through hole 60 can make sliver connect without difficulty on the one hand, prevents to damage the outer layer fiber by the sliver of cotton fiber be combined on the other hand.By this long narrow funnel-shaped hole, sliver has been compacted easily, becomes flat rubber belting shape structure from the distortion of circle strip structure.This flat rubber belting shape structure is very suitable for subsequently further processing in drafting system 5 or 6, and a kind of closely knit sliver combination may be provided, and that is to say a closely knit cotton sheet delivered in separately the drafting system to go to stretch.Do not have the gap for the sliver that makes these flattened cross-sectionals is adjacent one another are, guide thimble 58,59 and their through hole 60 dispose like this, make its width B ' on the X that overlaps each other.By being displaced sideways guide thimble 58 and 59, like that, the size X of this lap can accurately regulate shown in double-head arrow among the figure.The applicable cases that also has X size adjustment to 0.Yet this depends on the sliver material type separately that will process.In order to pool a cotton sheet from the flat sliver F of guiding sleeve pipe 58 and 59, the symmetry axis 61 of guide thimble 58,59 and 62 is obliquely installed with respect to vertical centering control branch plane V.That is to say that axle 61 residing vertical planes intersect below sliver parts 15 with axle 62 residing vertical planes.

Guide thimble

58,59 is fixed on

fastening pole

64 and 65 movably through connecting plate 57.A through hole is respectively arranged on the connecting plate 67, and screw 75 passes this through hole and is tightened on the guiding nut 71.This guiding nut 71 is to arrange like this, and it is to be bearing in the T shape pod 69 of

fastening pole

64 or 65 along

fastening pole

64 or 65 vertical movably modes.When screwing screw, the upper surface of nut 71 compresses the upper inside surface of T shape pod 69.Like this, vertically move and be lockable, guide thimble is fixed on its adjusting position.

One angle bar 72 is set on the fastening pole 64, and this angle bar 72 is fixed on the support 77 that schematically illustrates through screw 78.Especially as seen from Figure 14, angle bar has a slotted hole 66, by this slotted hole, can realize the whole lateral adjustment of guide thimble 58.Usually, a plurality of such angle bar are spaced apart and arranged on the fastening pole 64.Owing to exist this possibility that is displaced sideways fastening pole 64, just may regulate the side of the cotton sheet of transmission with respect to the inlet of drafting system subsequently.Certainly to fastening pole 65 same adjusting possibility can be set also.Yet on figure, just no longer drawn owing to very clear.

Adopting this guide thimble just can carry out specific inlet according to corresponding fibrous material regulates.In addition, the replacing of each guide thimble is quite convenient after wearing and tearing.

Figure 15 has provided the another kind of fixed form of sleeve pipe 58.The pole 63 of a band supporting member 68 is arranged on the sleeve pipe 58 of there, and supporting member 68 will be fixed on the bar 70 movably.In order to be locked in a preposition, a screw 73 that passes supporting member 68 is pressed to bar 70.Bar is fixedly supported upon on the support 77 in irremovable mode.As previously mentioned, a kind of device can also be arranged, can carry out whole lateral adjustment by traversing carriage 77 by means of its sleeve pipe 58.Can also imagine that the section of bar 70 is not circular, and adopts such design, and itself and corresponding supporting member 68 are being matched in shape, prevents guide thimble 58 distaffs 70 rotations.

Figure 16 has provided the another kind of embodiment of guide thimble 80, and its through hole 81 part therebetween narrows down.Guide thimble 80 is fixed on the angle bar 79 by screw 75 through connecting plate 67.Angle bar 79 image angle iron 72 the same being fixed on movably on the support 77.In addition, angle bar 79 has slotted hole in screw 75 zones, and this allows sleeve pipe 80 to be displaced sideways perpendicular to feeding direction.At guide thimble and fixedly can also imagine the variation design that other aspect the possibility.

Allow to do the star transmission according to feed unit as suggested in the present invention, and concerning sliver F, no longer need other assisted diversion position from the sliver of corresponding supply position 8.
