A round rotating comb is located under the lower clamp plate (12) and removes loose tufts (FB). Guides (32) vary the selected length of tufts removed or passed according to the fibre feed mode, maintaining the combed material within a minimum and constant separation range (E). The adjustable guide (32) regulates the gap (E) between the lower tong plate (12) and clamp line defined by the pair of opening cylinders (24) at the tong position of maximum advancement.
Description
Technical field
The present invention relates to a kind of gripping mechanism that is used for combing machine, it has a nipper frame that can move forward and backward, a nipper plate is arranged on the nipper frame, and the nipper plate that is positioned at pincers edge scope can form jaw or gripping point together with the nippers that is movably arranged on the nipper frame; Described gripping mechanism also comprises and is positioned at its inner feeding mechanism, be used for supplying with fibre material in the process of moving forward and backward of gripping mechanism, therefore, separate roller is to being installed in the downstream of gripping mechanism on the machine frame, the combing machine rotation is installed, and be arranged in the below of nipper plate, be used for carded fiber bunch.
Background technology
In fact, be necessary to regulate as required on the combing machine and will combing go out the ratio of (abbreviating combing machine waste cotton or noil as).The ratio of noil is between 5-20%, and this depends on the quality of yarn of being wanted, and yarn is to form through final spinning with the fibre material of combing.In addition, the fibre material (charging) that is provided also is provided the ratio of noil.
In other words, when the combing amount was big, long fiber was retained in the fibre material of combing, and staple fibre is almost completely discharged with the form of noil.Next these long fibers can be used to produce fine-count yarn, because fine-count yarn only needs less fiber basically on cross section on the yarn, and required yarn strength can not descend.The high nature of noil ratio has a direct impact output, and in final analysis, output directly influences the performance of spinning machine itself again.Therefore, the spinning machine operator is necessary to keep balance between required yarn qualities and the production loss that causes owing to combing out of noil.Therefore, the selection of degree of combing out is extremely important.Therefore in carding process, must be noted that and guarantee accurately to select fiber.
Known have many diverse ways combing machine and carding apparatus thereof can be adjusted to suitable combing out at interval.
A kind of method is the adjusting of spaces, and the distance between the pincers edge of spaces sign nipper plate and the clamp joint point of separate roller at interval.Spaces causes the amount of combing out big greatly, and spaces is little, and the amount of combing out is just little.In order to regulate spaces, need the shaft coupling on the rotary clamp axle, thereby make the position of vibration or pivoting of pliers that corresponding variation also be arranged, so spaces becomes big or diminishes to depend on how to regulate.In addition, the ratio of the fiber that goes out of combing also may be subjected to the influence from the feed type of feed roller.If raw material is from turn round forward barrel in (pre-run) process (forward feeding) of pliers, the amount of combing out is just less; If charging occurs in revolution backward (return-back run) process of feed roller (charging backward), the amount of combing out is just bigger.Because in the process of charging backward, almost all the circular comber that combs out in the process has all been supplied with in chargings, and the ratio of the fiber that combs out is big than in the forward feeding process also.It also is known principle that mixed feeding is provided, and in this case, a part of charging is directed to forward in the operation process, and remaining part is directed to backward in the turning course.For the charging of mixed form, also can regulate the amount of combing out by selecting feed type and spaces.
By above-mentioned adjusting, can partly realize good result, but staple fibre can repeat to enter in the fiber that combing goes out, this has adverse effect to the quality of being wanted.This situation can appear when especially being necessary to adopt big spaces for the ratio that increases noil.One increases the clamp joint point of separate roller and the distance interval between the pliers, and spaces will increase, and the length of related fiber also can increase in the distraction procedure of separating technology.The length of fiber is long more, and (weak point) fiber that floats that exists in this zone is just many more.These unsteady fibers are uncontrolled.As a result, can't determine whether these fibers are pulled away in separation process (of equal importance with distraction procedure), also can't determine subsequently comb out that they are retained or are combed out by circular comber in the process.
Summary of the invention
Therefore, purpose of the present invention provide a kind of can the as far as possible little device of constant maintenance spaces, thereby can realize the general proportions of traditional drawing frame, but when adopting a kind of charging of form, the ratio that can also regulate noil.
This purpose is by providing a kind of guide rail mechanism that is used for fibre material to realize, make that by means of this guide being used for the distance of this fibre material between the clamp joint point of feeding mechanism and gripping mechanism can regulate in accordance with regulations, the length of fiber cluster that wherein offers the combing machine section of circular comber can change, and the distance between the right pincers line of nipper plate and the described separate roller that is in the gripping mechanism front end at interval (spaces) remain unchanged.
Like this, spaces just can be optimized adjusting adapting to various fibre materials, and the described interval that is applied to the amount of combing out wanted does not descend.By this arrangement can guarantee each at interval under, by means of suitable mechanism, for example limit the mechanism in the path of the cotton sheet between the clamp joint point of fibre material or feeding mechanism (for example feed roller) and pliers, in separation process, can provide stable condition.In other words, spaces can be adjusted to minimum of a value, and this minimum of a value is approximate corresponding to the hauling distance in the traditional traction device.As a result, the ratio of uncontrolled fiber can reduce to minimum in the separation process.Simultaneously, under these conditions, the noil ratio also can change in special limited range as required.
In order to change the length of the fiber that offers circular comber, in the zone of described guide rail mechanism between the clamp joint point of feeding mechanism and gripping mechanism nipper plate above, and described rail sections guides fibre material below fibre material.
In this case, propose that in addition described guide rail mechanism is connected on the nipper plate in separable mode by securing member, the guide pass of guide rail mechanism can change on respect to the position of nipper in other words.
In addition, guide rail mechanism can be fastened to cotton sheet throughput direction transversely in the mode that pivots, and can carry out step-less adjustment or unlimited the adjusting like this.
Side direction guiding for cotton sheet is proposed in perpendicular to the side guide element that outstanding guide rail surface is provided for guide rail mechanism on the direction of guide pass.Like this, especially when the side of cotton sheet was directed in this zone, the end of lap will clearly be directed to the cylinder that is positioned at the downstream.
Preferably, the cross section of described guide rail mechanism can be a wedge shape, and from beginning to extend with the interactional feed roller of feeding-passage.
Other advantage illustrates according to the following examples.

The specific embodiment
Fig. 1 has provided known gripping mechanism 1 (abbreviating pliers as), and it can do pivoting action by crank arm 2,3 the assembling back.In this case, two the interior crank arms 2 of each shell that are installed in close circular comber 4 sidepieces are installed on the axle 5 of circular comber, for example install in the mode that pivots.On the part circumference of circular comber 4 combing machine section 7 is arranged.The other end of pivot arm 2 rotatably is fixed on the nipper frame 8.The pivot arm 3 of back (also can have two) is installed on the pincers axle 10 in the torsion proof mode.The free end that is positioned at the pivotal axis 3 of opposite side is connected on the nipper frame 8 in rotary manner by means of axle 9.
The inside of pliers 1 is a feed roller 27, and feed roller 27 rotations are installed, and are connected with driver element (not being shown specifically), and in order to carry the lap W that is directed by joint, feed roller 27 is done batch (-type) and rotatablely moved.Feed roller 27 has an axle 28, and feed roller 27 rotations are installed on this root axle, and the two ends of axle 28 are installed in the bearing holder (housing, cover) of nipper frame by bearing (not being shown specifically).Feed roller 27 is driven by known ratchet driver, and ratchet driver is by the motion control of nippers 14.But feed roller 27 also can be by the motion drive of nippers, and therefore, it can be subjected to for example influence of the crooked disk shown in the GB-PS933946.The imagination of being not difficult, the used crooked disk of this embodiment also can be directly installed on the axle of circular comber, for example shown in the DE-PS231797 like that.In the running forward and revolution of pliers, the driving of feed roller 27 may be affected, or even in the running forward and turning course of significant proportion.
Fig. 2 has provided the phantom that the pliers 1 in the proparea of pincers edge 30 of nipper plate 12 amplifies.Feed roller 27 belows, nipper 12 provide a feeding-passage 26, carry lap W for the direction along preceding pincers edge 30, and feeding-passage 26 interacts with feed roller.
A track element 32 is directly connected on the feeding-passage 26, and the cross section of track element 32 is wedge shape, is positioned on the nipper plate 12.Rail sections in this example has the track element 33 of two side direction, and this track element 33 vertically reaches on the guide pass 35 of rail sections 32.Visible Fig. 4 in position of the track element 33 of side direction, Fig. 4 provided Fig. 2 along X to partial view.From Fig. 4 also as can be seen, the track element 33 of side direction is positioned at each shell, and the boring 36 of depression is arranged on these shells, in each shell, for rail sections 32 is screwed on nipper plate 12, or for it being fastened on the nipper plate 12, screw 38 is inserted in the boring 36.This only is an embodiment of the method for fastening this device; Other the imagination of also being not difficult.Under any circumstance, this being fastened on when designing all will be easy to unclamp, and for example, rail sections can be by another rail sections with different size to unclamp.
Another embodiment of rail sections as shown in Figure 5, this rail sections is designed to guide rail plate 40 in form, wants and can pivot around axis 41 installing it.For guide rail plate 40 being fastened on the position of wanting, the guide rail strip has side direction bolt 42, and in each shell, side direction bolt 42 puts in the hole 43 on the side guide 45.In each shell, guide rail plate 40 and side rail 45 are secured together by nut 44, thereby it is fastened on the position of wanting.For example, these side rail 45 (only having provided among Fig. 5 a) are fastened on the nipper plate 12 by screw, and for the pivot 41 of mounting guide rail plate 40, side guide 45 also can have the placement unit (not shown).
The function of the rail sections 32 shown in introducing in detail according to Fig. 2 and 3 below.
Lap W after the expansion (not detailed showing) is introduced in the gap between feed roller 27 and the feeding-passage 26.By means of an intermittent drive means (not detailed showing), lap is carried 24 direction to separate roller.During pliers 1 moves forward 24 direction along separate roller (charging of turning round forward) or during moving backward (revolution charging), carry (or being called charging) to be affected.Be not difficult to imagine, during pliers turns round forward and turns round backward, also can arrange mixed feeding.
In Fig. 2, pliers 1 is in the most forward position (extreme position in the place ahead), and in this position, pliers 1 is open.The cotton sheet that leaves feeding-passage 26 is guided the top of the guide pass 35 of rail sections 32, and is deposited on the end of fiber V, and before this, fiber V part is sent to feedback, and cotton then sheet is transferred to the clamp joint point K of separate roller by the transfer movement of fiber.During described move subsequently, lap end (abbreviating fiber cluster FB as) enters in the broach zone of fixing comb 11.Because the fiber that separate roller to 24 rotation, is delivered among the fiber cluster FB of clamp joint point K is drawn out fiber cluster, and is bonded in the end of fiber V.In this case, the fiber that is called as " fiber floats " is also partly pulled out, because adhesion friction, these fibers fail to be retained in the lap.
In order to allow few this uncontrolled unsteady fiber in separation process, be handled, be necessary to allow spaces AL (distance between the clamp joint point KM in the clamp joint point K of separate roller and the feeding-passage 26) keep as far as possible little.The result is, clamp joint point K and be in and should keep as far as possible little apart from E between the pincers edge 30 of the most forward position.Distance E at interval is commonly referred to as spaces.What really will pursue is spaces, and it has bigger influence to traditional draw-gear.This has considered the controlled separation process that will take place, and the undesired staple fibre that will separate by the combing machine section 7 of circular comber 4.
In order to obtain higher degree of combing out, for example can adopt known solution, the result is that spaces increases; Adopt round comb method afterwards, long fiber cluster FB appears in the combing machine Duan Shanghui of circular comber.The result is, the more fiber machine section 7 that is combed attracts, and adopts the pliers 1 of sealing, and combing machine section 7 is no longer kept by the following clamp joint point KU of pincers edge 30 (seeing the dotted portion of Fig. 3) or pincers are got.By adjusting spaces E, can change the height of wanting that combs out really, but increase spaces, the condition in separation process or the distraction procedure can worsen.For fear of this situation occurring, recommend to use rail sections 32, like this, under the situation that spaces E remains unchanged, can change pincers and get ratio or combing ratio.In order to obtain consistent condition, must guarantee that lap W or fiber cluster FB are positioned at from the inflexion point UL of feed well to extend on the plane of clamp joint point K of separate roller in separation process; In other words, this plane defines the position of the guide pass 35 of used rail sections.
Fig. 3 illustrates to use different rail sections 32a and 32b what influence is arranged.
Because rail sections 32b is installed in guide pass 35b below again, so the traction between the following clamp joint point KU of inflexion point UL and pincers edge 30 is shortened.
The dotted line position of the pliers 1 from Fig. 3 as can be seen, in carding process, the length of the fiber cluster FB before the combing machine section 7 above the pincers edge are L2.Length L 2 suitable length L 1 (dotting) when using rail sections 32a, because in this case, the traction between the following clamp joint point KU of inflexion point UL and pincers edge 30 is longer.
In this case, pincers edge 30 geometry select by this way: the following clamp joint point KU that realizes with the pincers edge of nippers approximately is positioned at the lower range that clamps edge.Last clamp joint point KO is positioned at the jagged breach of pliers, and described breach extends from rail sections.But also can expect, can use other forms of pincers edge in this case.
Therefore, as required, can change the noil ratio, and need not to change the separation condition (or minimum spaces) of optimization.
The track element 33 of rail sections 32 side direction is further guaranteed edge guiding in separation process of fiber cluster with being cleaned, and its structure also can remain unchanged.
In the embodiment shown in fig. 5, in order to change the noil ratio, the setting angle of corresponding adjusting guide rail plate 40.In this case, the side guide of the fiber cluster FB in each example has replaced side guide 45, and certainly, side guide 45 still can correspondingly form.
