Abstract

According to the invention, the operation of a combing machine (1) may be improved, whereby each or pairs of feed rollers (6) are driven by an individual electric motor (7). By means of the above, the adverse effect of a blockage of a feed roller on other feed rollers, for example as a result of a lap formation, can be avoided. An arrangement of the motors (7, 7') such that they take part in the oscillation movement of the grippers (5), avoids the need for a control action to eliminate an additional rotational movement, imparted on the feed rollers (6) by the oscillating movement thereof about the drive motor.

Description

Multi-head combing machine

Technical field

The present invention relates to a kind of multi-head combing machine, it has the feed roller of attaching troops to a unit in each combing head, independent, is used for the nipper conveying combing cotton-wool to the nipper mechanism of swing.The combing machine that this all feed rollers drive by common driving shaft is the theme of DE 195 06 351 C2.

Background technology

Multi-head combing machine has eight combing heads usually.Each combing head has a feed roller, by it will combing cotton-wool be transported to combing mechanism as, nipper, fixing comb and circle comb.Described eight feed rollers constitute individually, and are arranged in the nipper mechanism of swing.They are fed through central authorities by the feeding motor of fixed-site and give axle by gear or cingulum, drive to form fit.

When the nipper mechanism swing, rotatablely moving of adding can be delivered on the feed roller, because feed roller is around the feeding motor swing of fixed-site.For balance it, the feeding motor must carry out with clamped plate motion synchronous, carry out front and back rotatablely moves this feed motion of stack feed roller like this that rotatablely moves, the feeding campaign that feed roller is only stipulated.

Form under the situation of twining on one of in feed roller, can cause the obstruction of feed roller, because all feed rollers are coupled to axle by feeding, this may cause the obstruction of all feed rollers.

Summary of the invention

The improvement mode.

It finishes this task by the feature of claim 1 or 6.By by synchronous single motor (its rotating speed and direction of rotation can middle ground adjust) to each or at least each two feed roller drive, obtain such advantage, i.e. the central adjustable of feed roller.Carry out single driving by feed roller, avoided the interactive shortcoming of feed roller combing machine.If the feed roller of each two adjacent combing head jointly drives by a single motor, this advantage also can keep basically.

If combing machine selectively has six or eight or more a plurality of combing head, this embodiment is particularly advantageous.In this case, combing machine is made up of three to five similar two combing heads.

According to claim 2, single motor and nipper axle journal arrange the advantage that provides such, i.e. the oscillating motion of not load of quality of single motor or only seldom load (if it is along with swing) nipper mechanism coaxially.In contrast, according to claim 4, the layout of single motor on nipper mechanism have such advantage, what promptly nipper mechanism, that the transfer movement of combing cotton-wool is worked oscillating motion needn't be by single motor rotatablely moves balance.

If single motor is arranged coaxially according to claim 5 and feed roller, then be need not transmission member and be used for rotatablely moving of single motor.

Single motor provides this possibility, discerns initial winding by the power consumption of monitoring it on feed roller and forms, and arrange to intervene.In contrast, the drive motors that is used for the central authorities of feed roller according to claim 6 provides the advantage of better simply structure.If all feed rollers are coupled to axle by common feeding, the reaction that also can avoid the obstruction of feed roller to cause according to claim 7 at this torque limiter so.

The specific embodiment

The view of the combing machine 1 in Fig. 1 to 4 just schematically shows preceding four combing heads 2 of the combing machine with at least six combing heads, and they are separated by middle standing pillar 3.The structure of this type of combing machine 1 is known, and therefore here is not described in detail and illustrates.

On each combing head 2, front and back swingingly are supported with nipper mechanism 5 on nipper axle journal 4.Nipper mechanism 5 keeps its about 15 ° oscillating motion by the transmission member of unshowned swinging transmission mechanism herein.Rotatably be furnished with feed roller 6 in each nipper mechanism 5, cotton-wool that will combing by this feed roller 6 is transported to nipper.Be provided with motor 7 for driving feed roller 6, the rotating speed of this motor 7 and direction of rotation can change apace and be reverse.Synchronous motor or stepper motor are suitable especially for this purpose.

In the embodiment of Fig. 1, each feed roller can drive by single motor 7.Its stator can be connected with flange with the nipper axle journal 4 of nipper mechanism 5 on the sidewall 8 of nipper mechanism 5 respectively coaxially, and along with ground swing before and after the nipper mechanism.The rotation of its rotor is delivered to form fit on the affiliated feed roller 6 by nipper axle journal 4 and the intermediate member 9 (as gear or cingulum) that can be rotated to support in the middle standing pillar 3.In the unshowned herein control device that rotatablely moves of single motor 7 as required combing factor (Auskaemm-faktor) and produce.Self-evident, all single motors carry out load with identical frequency and direction of rotation, and correspondingly run-in synchronism, and carry out same feeding on all combing heads 2.The embodiment of this single motor 7 along with nipper mechanism 5 swing provides this advantage, the rolling movement (Abrollbewegung) that the swing owing to nipper mechanism 5 that promptly needn't balance intermediate member 9 causes.

Single motor 7 also can with nipper axle journal 4 disalignments be installed in other, with the member of nipper mechanism swing synchronously on, substitute and be installed on the nipper mechanism 5.

By fixed arm 10 fixed-site be fixed on frame, for example on the intermediate studdle 3.The transmission that rotatablely moves of single motor 7 is finished as mentioned above like that.This embodiment provides this advantage, and the cable that power delivery is arrived single motor 7 is without undergoing the caused wearing and tearing of high hunting frequency owing to the combing circulation.

In the embodiment of Fig. 2, the feed roller 6 of each two adjacent combing head 2 drives by a single motor 7.This motor can be connected on the sidewall 8 of nipper mechanism 5 with flange as described above, and along with the nipper mechanism swing.This motor is by extend to nipper axle journal 4 next combing head 2, lengthening with on its transmission member 9 that is delivered to two combing heads that rotatablely moves always.But motor 7 also can be fixed by fixed arm 10 fixed-site ground as shown in FIG. 1.The merits and demerits of two kinds of embodiments is corresponding to described at Fig. 1.

In the embodiment according to Fig. 3, single motor 7 is arranged on the sidewall 8 of each nipper mechanism 5 coaxially with feed roller 6.It is unnecessary that transmission member on this feed roller 6 becomes.This embodiment requires light especially, low-quality single motor.In this embodiment, it is favourable that feed roller 6 is configured to cydariform motor (Trommelmotor), and the motor wherein outside, that rotating partly is configured to feed roller.Owing to lack transmission member, the effect of waving of balance therefore needing can not occur.

Fig. 4 shows a kind of embodiment at last, wherein the motor 7 ' that is swingingly connecting with the sidewall 8 of nipper mechanism 5 driven one continuous, driving feeding of feed roller 6 by intermediate member 9 and giving axle 11.Motor 7 ' also can that is to say that the motor of two, four or eight reduced sizes replaces by a plurality of, and they are distributed in to act on to feed on the length of combing machine 1 gives axle 11.

Because under this situation of feed giving axle 11 that is being coupled all combing heads 2, combing head with obstruction fault (as form twining) may cause the disadvantageous reaction to other combing head, therefore in other schemes according to the present invention, stipulate, in the chain of transmission member 9, insert slip-clutch.This slip-clutch transmits reliably and is the required moment of conveying lap, and can throw off when feed roller blocks.The single interruption that forms standard on combing machine of combed sliver will make the operator note this fault, thereby they can intervene.

When forming winding, other combing position is produced less influence thus.Continuous feeding under the situation of giving axle, feedback only once also is necessary for the actual value that detects the accurate angle ground feeding of feed roller, and this influences the cost of system significantly.
