Summary of the invention

Therefore, the present invention is based on following purpose: a kind of circular comb of the type mentioned at the beginning is provided, characteristic with it is previously known Embodiment compared to being improved.

In order to realize this purpose, a kind of circular comb of feature with Patent right requirement 1 is provided.Circle according to the present invention Comb is included with external circular comb main unit；Combing section with multiple combing sticks, the combing stick are arranged in the circular comb On the outside of main unit and equipped with outwardly projecting combing tooth, so that when looking up in combing side, preceding comb Reason tilts on each leisure in the flank portion combing direction；And aligned segments, simultaneously equipped with multiple outwardly projecting aligning parts And be arranged on the outside of the circular comb main unit, so that when looking up in combing side, preceding aligning parts side Respectively relative to the inclination of combing direction, and some of which at least substantially looks up in combing side and arranges when around.

It has been found that in the case where the nip rate of the carding machine is up to 600 turns per minute of the high speed of service, two fibers It (is on the one hand in other words, partially the fiber part that initially comb and then newly comb, on the other hand to be protected by traction roller The part for the previous carded fiber held) it is exposed to sizable power, there may be air and/or fiber whirlpools for this, and therefore It may cause (in other words, when two fiber parts link together) during combination if not taking fair game Scrambling.In order at least avoid such case to the full extent as far as possible, circular comb according to the present invention has aligned segments, Middle aligning parts especially generally radially protrudes outward.

Aligning parts can for example be configured as alignment tooth, alignment pins or like.Alignment tooth especially can have not Same tooth geometry, and preferably can be the integral member of zigzag slit, jaggies part or grooved metal gasket.With comb Manage that tooth is the same, and aligning parts is made of metal material, and preferably mechanical rigid.

According to the present invention, these aligning parts respectively have preceding aligning parts side, and the preceding aligning parts side is respectively It is oppositely tilted with combing direction, in other words, aligning parts especially has negative component face angle or face angle.

This is in alignment with component and combs the combing tooth difference of the combing stick of section.The combing tooth is also especially substantially It protrudes outward, but comb tooth there is preceding combing flank portion, is combed before described on each comfortable combing direction in flank portion in the radial direction Inclination, in other words, with positive face angle.This positive face angle is referred to as toe joint close angle.Comb tooth with especially by pressing from both sides Pinching device assembly holding and the required combing of fabric fibre still to be combed engagement is due to this positive face angle.Comb the comb of stick Tooth covering combing circumference angular region is managed, and generally forms the practical combing region of circular comb.

However, on the other hand, aligning parts does not need this combing engagement.Exactly, aligning parts is configured to pair Standard, guidance, parallelization, stretching and/or it is especially to maintain the fiber combed being fed back by traction roller, to be shelved on down On portion's traction roller.This does not need positive combing engagement.Positive combing engagement can even run counter to desire.In fact, being intended to phase To gently contacting the fiber for being fed back into and having combed.This soft fiber contacts are particularly due to the negative portion of aligning parts Part face angle or face angle.Aligning parts is arranged on the outside of circular comb main unit, especially to divide tangentially and preferably axially The mode of cloth, so that the soft fiber contacts be allowed preferably to occur from anywhere in the region of aligned segments.Due to The fact that some aligning parts are front and back arrangements when combing side looks up, this soft fiber contacts even can be preferably every A circulation (in other words, during the primary rotation of circular comb) occurs several times.Generally speaking, this causes to be fed back into and comb Particularly efficient alignment, guidance, stretching and/or the parallelization of fiber.In addition, which ensure that these fibers and lower part traction roller Good contact.Even if under above-mentioned high machine speed, it ensures that highly uniform cohesive process, to generate uniform fine Dimension top (=be placed in a manner of stacking the fiber of embarking on journey combed) on traction roller.These fibers, which can handle into, to be had The high quality yarn of much lower yarn error (thick and thin place).As a result, obtaining the yarn with low CV value, CV value is yarn The index of the line uniformity.

In addition, the circular comb according to the present invention with aligned segments allows for the very high nip rate of carding machine, together When ensure the constant high quality of fibre structure at the top of carded fiber.600 turns of nip rate up to per minute or even more The high speed of service is possible.Further, since the design of aligned segments, the manufacture of aligned segments is cheap, is especially similar to combing The design of section.

In the simplest case, the circular comb main unit of circular comb according to the present invention can be by single-piece circular comb main body structure At.However, single-piece circular comb main body also may include multi-section cyclotomy comb main body.In addition, single-piece circular comb main body can have volume Outer optional component, for example, especially circular comb, is fastened to the axis of carding machine by securing bracket.Circular comb main unit or at least circular comb Main body itself especially can substantially have the basic configuration of the circumferential segment of hollow cylinder, wherein the cylinder of hollow cylinder Axis be circular comb main unit especially with the longitudinal center axis of rotation axis coincident.Therefore, the outside of circular comb main unit It is preferably also at least substantially the shape of pitch cylinder.This is particularly suitable for the region of arrangement combing section；However, this can also be fitted For the region of aligned segments to be arranged.In front immediately in aligned segments or the region in aligned segments, the outside of circular comb main unit It especially also can have and the variform geometry of accurate pitch cylinder.Although this geometry can be with accurate pitch circle Post shapes are different, but outside usually can especially be interpreted tangential external or outer circumferential sides.

Position or orientation term used herein respectively especially the rotation axis of spindle or thus rotation axis limit Cylindrical-coordinate system.In this context, term " axial direction " refers to the orientation on rotation axis direction, and term " radial direction " refers to vertical Directly in the orientation of rotation axis, and term " tangential " refers to the orientation about rotation axis in a circumferential direction.According to the present invention Circular comb combing direction especially circular comb surround rotation axis rotation direction of rotation.Direction is combed especially about rotary shaft One in two circumferencial directions of line.

In order to comb textile fabric 2, two combing components are provided, i.e., on the one hand, are fastened to the top comb for pinching device assembly 3 12, and on the other hand, the axis that can be rotated around rotation axis 13 is fastened in particular by means of single-piece or multi-piece type installation unit 15 14 circular comb 16.Rotation axis 13 can also especially be construed to the longitudinal center axis of circular comb 16.It is limited relative to rotation axis 13 Cylindrical-coordinate system with the axial direction z oriented along rotation axis 13 (referring to Fig. 3), wherein radial direction r along relative to The range direction of rotation axis 13 orients, and tangential direction φ is oriented along the circumferencial direction around rotation axis 13.

Circular comb 16 has various component parts.Circular comb, which has to have, is respectively fastened to its outside 18 by means of fastening strip 21 Combing section 19 and aligned segments 20 circular comb shape main body 17, wherein especially means of dovetail grooves geometry and/or T-slot geometric form Shape is applicable.Alternatively, it can also be fastened by glued, compacting and/or clamping.Combing section 19 is by being fastened to outside 18 Multiple combing sticks 22 are constituted.In the illustrated exemplary embodiment, it is equipped with four methods stick 22 in total, by the axial direction The zigzag slit that (in other words, on the direction of rotation axis 13) front and back is arranged is formed, and has the comb projected radially outwardly Manage tooth 23.The whole covering combing angle of circumference of combing stick 22, formed effectively combing region and can for example, by using 78 °, 90 °, 111 °, 137 ° or 180 ° of value, and other values of the range between 75 ° and 150 °.Shown including four In the exemplary embodiment of a combing stick 22, combing angle of circumference covers about 90 ° of angular region.

Aligned segments 20 also have multiple component parts, i.e., three 24 (its of align bar in the illustrated exemplary embodiment Similar to combing stick 22), by that will have the zigzag incision of the alignment tooth 25 projected radially outwardly front and back in the axial direction It arranges and forms three align bars.

In the exemplary embodiment of circular comb 16 shown in Fig. 1, aligned segments 20 abut directly against combing section 19.Aligned segments 20 exist The rear of combing section 19 is set on combing direction 26, and axis 14 and the circular comb 16 being therefore fastened thereon surround rotary shaft Line 13 rotates.It combs direction 26 and corresponds to tangential direction φ.

It aspirates case lid 27 and abuts separative unit 6 from below, the suction case lid 27 especially seals the largest portion of circular comb 16.

The combing stick 22 of combing section 19 is provided with corresponding cover board at each of two axial forward end place.In order to illustrate The design for combing stick 22 has been omitted from the cover board of the combing stick 22 adjacent with aligned segments 20 in the view of Fig. 1 and 2.This is provided The design for being best understood from, and especially combing tooth arrangement and orienting to the design of the combing tooth 23 of combing stick 22.

As shown in Figure 2 in Fig. 1 shown in the amplification detail view of highlighted section II, combing tooth 23 be different from pair Quasi- tooth 25.Combing tooth 23 respectively has preceding combing flank portion 28, tilts on combing direction 26, in other words, with phase For the positive face angle ZK of radial direction r.On the contrary, alignment tooth 25 respectively has preceding alignment flank portion 29, alignment tooth and combing side It is oppositely tilted to 26, in other words, there is the negative face angle ZA relative to radial direction r.The exemplary implementation shown in In example, the face angle ZA of alignment tooth 25 has -10 ° of value.

As from it can also be seen that alignment tooth 25 protrudes past zigzag slit band by protrusion V in the detail view of Fig. 2 Bottom.In the illustrated exemplary embodiment, this protrusion V is 1.75mm.

When rotating around rotation axis 13, the combing tip 30 for combing tooth 23 is moved up in cylinder combing envelope 31 It is dynamic.On the contrary, the alignment tip 32 of alignment tooth 25 does not reach this combing envelope 31.At alignment tip 32 and combing envelope 31 Between there are free clearance, the radial extention range D of free clearance is differed always in the exemplary embodiment shown in Fig. 1 and 2 Oppositely increase in zero, and also with combing direction 26.Therefore, compared to combing tip 30, tip 32 is directed at away from rotation axis 13 radial distance is smaller.In the illustrated exemplary embodiment, expanded range D (=radial distance) and combing direction 26 are reversed Ground increases to 6mm from initial 3mm.

Fig. 3 shows one of align bar 24 on the direction (in other words, perpendicular to combing direction 26) of rotation axis 13 Cross section sectional view.This cross section is highlighted in Fig. 2 with III.Fig. 3 shows the square upward axis in rotation axis 13 The three zigzag slit bands arranged before and after to ground, zigzag slit band are each provided with the alignment tooth projected radially outwardly 25.Between zigzag slit band, intermediate washer 33 is arranged so that clear passage 34 is formed in axial direction in each case Between neighbouring alignment tooth 25.These clear passages 34 respectively have aisle spare E, in the illustrated exemplary embodiment, lead to Road area E is perpendicular to 1.25 times of one cross-sectional area F in the alignment tooth 25 that combing direction 26 orients, and regards feelings Depending on condition, cross-sectional area F can be a part of the bottom of zigzag slit band.Cross-sectional area F includes corresponding right A part of the bottom of quasi- tooth 25, and depend on the circumstances, it can be the alignment tip 32 that alignment tooth 25 is set and middle pad A part of the bottom of zigzag slit band between the top edge of piece 33.In detail view shown in Fig. 3, two correlation surfaces Product each different hacures of using by oneself of E and F highlight.

In the illustrated exemplary embodiment, the aisle spare E of clear passage 34 is kept constant on combing direction 26.? In unshowned Alternative exemplary embodiment, aisle spare E and the combing direction 26 of clear passage 34 are oppositely continuously reduced.

The function of circular comb 16, the especially function of aligned segments 20 is described in more detail.

Carding machine 1 pinches rate operation with the high of 600 turns of circular comb 16 for example per minute.As a result, the strength generated applies On textile fabric 2 still to be combed, but also it is applied on the textile fabric 11 combed.Purpose be avoid it is resulting not Good consequence.A kind of countermeasure is in alignment with section 20, especially influences the textile fabric 11 combed.It has been combed to accommodate and be discharged Textile fabric 11, the traction roller 7 to 10 of separative unit 6, which executes, retreats movement.In order to which the textile fabric 11 combed is discharged, draw Roller 7 to 10 rotates in its corresponding forward direction.It is presented accommodating by the removable top comb 12 for pinching device assembly 3 and being fastened thereon Before the new portion for having combed textile fabric 11 sent, traction roller 7 to 10 slightly rotates in the opposite direction, so that previously The textile fabric 11 that combed accommodated is fed back into a little from first pair of mutually opposed traction roller 7 and 8.Then, by nip device group The new portion for having combed textile fabric 11 that part 3 and top comb 12 are fed rotates in the forward direction period placement in the next of traction roller 7 to 10 Combed textile fabric 11 this be fed back on part, and be bonded thereto.

In order to most preferably carry out this connection or cohesive process, it is important that the combing being fed back by traction roller 7 to 10 The part of textile fabric 11 is shelved on as snugly as possible on the first lower part traction roller 7.Due to the high running speed of carding machine 1, Always do not meet this condition.There are following situations: drawing with the first lower part the part that is fed back into for having combed textile fabric 11 Roller 7 separates, so that these have combed the vortex of textile fabric 11.This is undesirable.Therefore, circular comb 16 is provided with aligned segments 20 to offset this influence.The alignment tooth 25 (alignment flank of tooth 29 and combing direction 26 oppositely tilt before it) of aligned segments ensure by The part that traction roller 7 to 10 was fed back into combed textile fabric 11 is guided, is aligned, stretching, homogenizing and/or parallelization. Especially, aligned segments 20 another effect is that, combed textile fabric 11 this be fed back into part shelve as snugly as possible On the first lower part traction roller 7, easily connects or be integrated to and combed textile fabric 11 so that this be allowed to be fed back into part New accommodating portion.

This is promoted by being directed at the negative face angle ZA of tooth 25.The negative face angle ZA of alignment tooth ensures to have combed textile fabric The gentle contact of 11 fiber for being fed back into part.Engagement is not combed.Especially, combed textile fabric 11 is fed back into portion Point fiber not will receive with comb tooth 23 engaged with the combing for the textile fabric 2 for still needing to be combed during due to positive face angle ZK and the comparable tractive force of tractive force generated.Be also with the relatively gentle contact for being fed back into part for having combed textile fabric 11 by It is bigger in the distance away from alignment tip 32.In addition, radial distance D and freedom between alignment tip 32 and combing envelope 31 Channel 34 is used to be maintained upward by the air-flow 34a by the first lower part traction roller 7 in the side of suction case lid 27.Generally speaking, this is true The required close contact for being fed back into part with the first lower part traction roller 7 for having combed textile fabric 11 is protected.

Fig. 4 shows the another exemplary embodiment of the circular comb 35 for carding machine 1.Circular comb 35 have with as circular comb 16 Combed textile fabric 11 be fed back into the identical above-mentioned beneficial effect in part.It is with the most important difference of circular comb 16, circle Comb 35 has two parts circular comb main body 36, is made of the first main part 37 and the second main part 38, and combing section 19 is fastened to First main part, and aligned segments 20 are fastened to the second main part.Two-piece type circular comb main body 36 can also be interpreted to wrap Include the circular comb main unit of the first main part 37 and the second main part 38.

The another exemplary embodiment of circular comb 39 shown in Fig. 5 has again and has combed being fed back into for textile fabric 11 The identical advantageous effects in part.Just as circular comb 16, circular comb 39 only has single-piece circular comb main body 40.Most important difference is, The alignment tip 32 of alignment tooth 25 is in each circumferential position covered by aligned segments 20 with the perseverance equal away from combing envelope 31 Set a distance D setting.In the illustrated exemplary embodiment, this radial distance D is 2.5mm.
