In order to reduce the number of moving parts, to increase the rotational speed of the combing machine and to improve the quality of the combed slivers produced, the device is designed so that the upper pull-off roller (5) is located close to the path of motion of the tips of the combing sector of the circular comber (1) and that the lower pull-off roller (7) pivots about the axis of the upper pull-off roller (5), in accordance with a given law of motion, through the path of motion of the tips of the circular comber (1).
Description
The present invention relates to a kind of combed cotton or like the device of cotton fiber, it has the nipper of a gripping fibers during combing; A circle comb, it has a combing sector that is used for combing by the nipper gripping fibers; The separator of fixed-site in fact is used for releasing by the good fiber of circle comb combing from nipper, is made up of at least one lower pull-off roller and the upper pull-off roller with its axially parallel; A top comb is used for the back side that combing pulls out fiber; And a sliver take off device.
Combed cotton or like cotton fiber, the basic conception in combing zone is succeedd on combing machine, wherein separate roller by position stability be placed in combing tip tracks the outside (for example: European patent EP 210764B1).
The pair of separated roller, by at the bottom of one and upper pull-off roller form, directly be adjacent to nipper device and circle comb.
Lower pull-off roller and constitutes the clamping gap of sliver with upper pull-off roller jointly between the tracks and upper pull-off roller of circle comb combing tip.
Nipper configuration be along both direction by swing type supporting.
On the other hand, it moves towards the most advanced and sophisticated tracks of the combing of circle comb to separate roller one determining deviation from this.Carry out the combing of fiber pile in this position by the circle comb.
After this process finished, the nipper device so rose as a cell cube, caused the smooth fiber pile of combing to arrive the front of separate roller to clamping gap.
When this moved, the nipper device was also flatly near the separate roller gap.
At this time point, the sliver section that returns and the most advanced and sophisticated overlaid of the fiber pile of combing again are pressed in the clamping gap of separate roller, and by separate roller along extracting direction out by pull.
Top comb is inserted into the terminal of the smooth fiber pile of combing simultaneously, and combing goes out fiber element freely.
By the drawback movement and the right extraction campaign of separate roller of nipper device, the fiber pile of combing is separated, and new fiber pile enters on the nipper device through feeding roller, is held and arrives the circle comb and enter the combing position.
Such arrangement is disadvantageous, because especially the nipper device must be carried out motion very inequality with high acceleration more or less.
Operating rate is because following former thereby be restricted significantly, that is: to produce be strong to noise, and the inertia force that is occurred can cause exceeding average wearing and tearing.
In addition, have only when the machine quiescent period and just can adjust spaces and feed rate.
Another decisive shortcoming is: the free end of the fiber pile that is combed smooth, with higher speed its freely fiber tip move ahead, cross the motion of long distance, and must be placed on the recovery end place of sliver with the position of accurate definition.
Relevant with air drag at that time with the air swirl that occurs, it is that often generation is only defective that the fiber pile is placed on the sliver of recovery, so people are forced to lower rotary speed working.
In any case but the mass loss in sliver is confessedly.
Another shortcoming of well known device is: separate roller to and take off between the roller and uncontrolled wrinkle to occur and form, it is that Pilger reciprocating by separate roller produces, it additionally causes disturbing defective in the combing process.
The purpose of suggestion is by means of European patent EP 0406589, gets rid of some above-mentioned defectives, firmly arranges nipper device and separate roller in round circumference range of combing by the position.
The fiber pile of single face combing should be caught and clamp to an additional transmission clamp in the clamp scope, and cross the combing tip tracks of circle comb, imports in the right clamping gap of separate roller.
Simultaneously, the return terminal of fiber pile is combed extraly by utilizing circle comb section.
Such device is favourable on the surface only.
Between two paths of circle comb section by the transmission clamp must finish so many complexity and because the arbitrary motion of fiber pile strengthens the motion of difficulty, so that the revolution of combing machine must reduce extraly in the face of the described combing machine of beginning.
Owing within the effective range of transmission clamp, do not carry out combing process, and only under the given way of chance, can finish welding process, under desirable form so mass parameter neither can realize.
Based on this reason, use swing type nipper device (EP0558441) to carry out work in practice all the time, and be with all its shortcomings described above.
Present task of the present invention is: realize a kind of combed cotton or like the device of cotton fiber, the machine components quantity and weight of its swing should reduce significantly, and between combing process and welding process, can reach the guiding of high precision ground exactly by the round fiber pile of combing combing.
About the overlap joint degree, the adjustment possibility of separation length and feed speed also should guarantee during machine run.
Another object of the present invention is to: to so guiding, so that can avoid the outstanding sex change of fabric at separate roller and the sliver that takes off between the roller.
Achieve a solution by the defined feature of claim 1 according to task of the present invention.Constitute by means of this, upper pull-off roller can be placed very near the tracks of justifying the combing tip of combing.
Therefore, the zone that is combed is very combed near the fiber pile in the clamping gap position by circle.
In addition, by lower pull-off roller takes off the lower curtate of roller round the top swing, clamping gap is towards the fibre tip motion of the smooth fiber pile of combing.
Meanwhile, the return terminal of sliver is held in the end in this wise by the air-flow of following combing sector and takes off on the roller, think the fiber pile big opening angle all set that inserts new combing.
A whole set of nipper device fundamentally is placed position stability.Need the quality of motion to be eased down to minimum.
During machine run, also can regulate spaces without a doubt by mobile nipper device.Similarly also be suitable for adjusting the feed amount of each combing jaw by means of feeding roller.
The mechanical movement of finishing between two paths of combing sector only is confined to the swing of lower pull-off roller, and it can be carried out according to the optimized characteristics of motion.
At last, this new equipment can realize significantly improving the operating rate of combing machine under extremely low device consumption.Can improve the quality of sliver simultaneously by the sliver fibre end and the accurate location of the fiber pile of new combing significantly.
Verified: with the bearing of upper pull-off roller, the bearing of end holder arms and the bearing of feeding roller in principle, carrying out the fixed setting of frame according to claim 2 has significance.
Used one second separate roller according to claim 3,, be not directed with always having the Zhe of wrinkle to guarantee the sliver in this zone at separate roller with take off and guide sliver between the device exactly.
Realize low device consumption by means of formation according to claim 4.
Device according to claim 5 constitutes, and can realize the optimization of Pilger paces at the intermittence motion of separate roller on the one hand, and realizes that second lower pull-off roller guiding sliver is to the mutually harmonious motion of taking out lower device.
By means of claim 6, the swing of lower pull-off roller has been defined best drive unit.
Sliver is adjusted in permission simultaneously according to the program of manual or automatic setting the uniformity that is provided with according to claim 7.
It is verified that according to claim 8 described top comb to be set can be favourable around upper pull-off roller swing.Thus, when top comb during in optimum mode of operation, the consumption of device has reduced.
Constitute by means of device, can adopt simple technology essential factor, during combing process,, regulate spaces and inlet amount by the change in location of nipper device according to claim 9.
By means of claim 10 definition standard, it is considered and is used for determining that relevant its of second lower pull-off roller takes off the forms of motion of the swing of roller around the top, is not having under the wrinkle Zhe storage combing suede bar circle situation.
Below in conjunction with accompanying drawing embodiments of the invention are described in detail:
Fig. 1 represents the sectional drawing according to apparatus of the present invention, directly after along with welding process, and before (combing machine) separation process;
Fig. 2 represents the device according to Fig. 1, when circle comb fiber pile;
Fig. 3 represents the device according to Fig. 1, when the good fiber of overlapping combing with when returning sliver;
Fig. 4 represents the movement profiles of the Pilger back and forth movement that paces move at intermittence of lower pull-off roller and the rotation of corresponding separate roller;
Fig. 5 represents the schematic diagram of vibratory drive, by a coupled drive case, and its crank and the rotation synchronously of circle comb; And
Fig. 6 represents to regulate the signal regulator of spaces.
The basic structure of this device should be set forth according to Fig. 1.
Circle comb 1 can be rotated to support on the support of combing machine in a conventional manner, and is driven in a generally known manner.Circle comb 1 has a combing sector, and its combing tip rotates on circuit orbit.
Near the track of combing tip, the end nipper 3 of nipper device 3,4 is set on the top of 1 of circle comb.This end nipper 3 is combed 1 tangential direction and is combed radially adjustable to circle along circle in a preferred manner.
Usually the top nipper 4 with an oscillating movement is arranged on the end nipper 3, and top nipper 4 has a clamping area and the deflection lug boss for the fiber pile for the treatment of combing, and it aims at the tracks of combing tip.
Supporting separate roller 5 near the tracks of top nipper 4 and the tracks of close combing tip with the frame fixed form.Its circumference is almost tangent with the tracks of the combing tip of combing machine circle comb 1.
This upper pull-off roller 5 at least with lower pull-off roller 7 cooperation, the latter is supported on the lever, can be round the axle swing of upper pull-off roller 5.Two separate rollers 5,7 mutually each other sliver 8 constitute the necessary clamping gap of welding processes.
Lower pull-off roller 7 is from a position, and it is positioned at outside the tracks of circle comb 1 combing tip fully, enter within the combing tracks, and near the clamping area of end nipper 3, be movable.
Second lower pull-off roller 6 also is that the axle around upper pull-off roller 5 can rotating (roller 6 also can be called deflector roll).Sliver 8 is by this separate roller 6, determines at the clamping gap of separate roller 5,7 and takes off between the device 9, and do not have wrinkle.
Owing to take off the unloading campaign of device 9 and the reciprocating motion of first lower pull-off roller 7, under the corresponding formation situation that Pierre's form paces of separate roller 5,7 move, two lower pull- off rollers 6,7 can be bearing on the common swing type lever.
Yet also can move second lower pull-off roller 6, not rely on the swing of first separate roller 7, and only have the guiding function of sliver 8.
By means of above-mentioned operation element combing process is described below.Usually the fiber pile that import and that clamp from end nipper 3 and top nipper 4 from feed roller 15, traditional mode is combed by the combing tip of circle comb 1.Comparison diagram 2.
During this period, lower pull-off roller 7 is positioned at outside the tracks of circle comb 1 combing tip.Sliver 8 remains in separate roller 5,7 clamping gaps at its return terminal.The sliver 8 that is positioned at separate roller 5,7 and takes off between the device 9 passes through along second lower pull-off roller 6 with the non-wrinkle tension-free form that reaches in the ring-type mode.
If this combing process finishes, combing sector is that lower pull-off roller 7 unclamps (disconnection) path.According to Fig. 3, this separate roller 7 is below upper pull-off roller 5, and crossing the combing tip is tracks swing freely now.
Simultaneously, the return terminal of sliver 8 returns by corresponding the rotatablely moving of separate roller 5,7.The return terminal of this sliver 8 by along with combing a little flow air also be pressed downward, cause preparing what a bigger angular aperture precision like this, so that insert the smooth fiber pile of combing.
Two fiber piles are piled up regularly, and by at the clamping gap that lap moves, each other being linked together (welding) by pressure owing to the rolling of separate roller 7.
During this process, top comb 10 is inserted in the fiber pile round upper pull-off roller 5 by its tip, and comb removes the return terminal of this fiber pile.
Simultaneously, nipper 3,4 closures of nipper device.New fiber pile is that combing process is ready.
Has untied from this fiber pile the new termination of sliver, and according in the clamping gap that remains between the top and bottom separate roller 5,7 shown in Figure 2.
In described device up to the present, combing process is played conclusive lower pull-off roller 7, be supported in the identical swing element as second lower pull-off roller 6, separate roller 6 preferably is used to tensioning and is positioned at clamping gap (5,7) and unloads sliver 8 between the lower device 9.
In the case, the swing of separate roller 5,7 and rotatablely move and to approach the condition of best combing process as much as possible.
Yet, in view of separate roller to after 5,7 to the accurate guiding of sliver 8, must carry out some rational formations.
Two processes, the guiding of combing process and sliver 8 has only when two lower pull-off rollers 6 and 7 can be optimized when swaying direction can be driven independently of each other.
For the common separate roller 6,7 that drives this swing, for example can arrange transmission mechanism according to Fig. 5.Here, the actuation movement of coupled transmission mechanism is directed out from crank (angle ) on circle comb 1.
The oscillating motion that is produced is carried out such improvement by the particular arrangement of another one four chain mechanisms, to reach motion diagram according to Fig. 4 angle of oscillation ψ.
By such oscillating motion, the combing cycle in contrast to can expand welding interval widely.This accords with the textile industry specification requirement of best combing process.
In curve map (Fig. 4), curve fVAR represents the clamping line of separate roller 5,6 and unloads the distance function of the clamping line of roller 9.If with fixed amount (for example 10mm/ combing jaw) addition of operation, then obtain between separate roller, to guide necessary sliver motion fGES for the sliver of no wrinkle.
Considering that additionally lower pull-off roller 6,7 under the situation of the unwinding campaign on the upper pull-off roller 5, can be defined as the feed total amount of the necessary upper pull-off roller 5 of combing process when between the shaking peroid of lower pull-off roller.
Provide the programmable electric driver of use to expend now and make under the situation that the optimized motion of aforesaid operations element becomes possibility at minimum machinery.
Therefore not only can finish separate roller 5,6 by means of computer-controlled stepping motor or servomotor, 7 oscillating motion but also can carry out rotatablely moves.
Under such type of drive, control first lower pull-off roller 7, regulate combing process in the best way by such motor, conform with purpose.
In contrast, the oscillating motion of second lower pull-off roller 6-do not rely on combing process-it controls by means of computer program, and this program was oriented in the guiding of reliable sliver 8 before unloading roller 9.
For reaching this purpose, the nipper device 3,4 at link rod 13 places is arranged on the swing arm 14 in order to swing, and is supported on frame by means of screw-and-nut-transmission device 11,12, and can regulate.Screw-and-nut-transmission device 11,12 can manually or by means of control motor (not shown) be operated.
When adopting such regulation device at 11,12 o'clock, feeding roller 15 can not relied on nipper device 3,4, be bearing on the frame to fixed-site.Therefore carrying out its driving by computer-controlled step-by-step movement or servomotor is no problem can the realization.
The layout of this transmission device also allows to implement certain regulation process with regard to the uniformity of sliver 8 during machine run for various executive components.
If for rotatablely moving of upper pull-off roller 5 disposes measuring unit and control module to motor, and computer control motor, and then uniformity can be determined and regulates according to the recoverable program.
Device described here can be improved with least identical modification.
Therefore, for example not mandatory provision: lower pull-off roller 5 must be supported by support in any case regularly.
With regard to the optimization meaning of all motions, this upper pull-off roller 5 also radially towards circle comb 1 or towards nipper device 3,4, is moved a little and conforms with purpose.
Have and conclusively be:
-to be flattened the fiber pile that combing gets off be not to move transverse to its major axis along big path in uncontrolled mode,
-clamping gap passes through to roll together with the return terminal of sliver, moves towards the fiber pile, and
-the sliver that returns swingingly is placed on the new fiber pile according to certain angle.
