This explanation will at first relate to some " routine " combing heads shown in Fig. 9 and 10, so that provide a basis to the explanation of each embodiment of the present invention for the back.Above-mentionedly in first to file, shown such an embodiment, and some accompanying drawings of this application are included among Fig. 1 to Fig. 8 once more, so that provide a starting point for change type shown in other accompanying drawing.

Only illustrate that at each accompanying drawing shown in this application operation of the present invention is those important combing machine parts.And, only those direct operating procedures relevant with the present invention are described.People can find the more complete explanation to combing machine, for example, at Virginia, USA summer Lip river Supreme Being Weir (Charlotteville, Virginia) reference book " drafting, combing and the rove " (Drawing by Zuo Ertan S. Si Zuoluoji (Zoltan S.Szaloki) work of weaving engineering college publication, Combing and Roving) find in, this reference book is on the 3rd of " institute's Textile Engineering book series " (The Institute Series on Textile Processing) that this institute publishes.

Contrast this background technology, the combing head that illustrates in Fig. 9 comprises that the lap of a rotation holds volume roller 100, a rotating drive shaft 102 that is used for combing cylinder 111, a nipper power transmission shaft 103 and a pair of separated roller 104 of planting 120, one rotatings of cylinder pin holder of pin is housed on the combing cylinder 111.Nipper power transmission shaft 103 is equipped with a crank arm 105, the rear end of nipper component 60 62 place's rotors be connected on the crank arm 105.The front end of nipper component 60 pivotally is connected on the connecting rod 67, and connecting rod 67 can be around the axis swing of the power transmission shaft 102 of combing cylinder 111.

Nipper component 60 also comprises base plate or nipper plate 63, and its front end (not having special expression) is suitable for forming a clamping jaw K who cooperates with the nippers 68 of corresponding formation.Nippers 68 is installed in primary structural component with nipper component 60 on the hinged bar 65 in 69 places.The so-called cotton roller 110 adjacent back of giving at nipper 63,68.

So far, these parts described in relevant Fig. 9 are formed the main working parts of combing devices, carry out the major function of combing machine.Because the combing action itself directly do not comprise in the present invention, and its detailed content can obtain (for example above-mentioned reference book) in the literature, therefore do not elaborate here.What prove absolutely here is that lap or the fibre sheet for the treatment of combing are transported to cotton roller 110(and transport by a system.To illustrate in greater detail below) and cooperate with guide plate 66 there and deliver to the jaw K that forms by nipper 63 and 68.The fiber that stretches out from jaw carries out combing by the card wire of cylinder pin holder 120, transmits by nipper then, and the fiber that stretches out with the rear portion of detaching roller 104 must carry out " splicing ".

After new noil must being placed on the fiber palpus that stretches out from detaching roller when nipper, nipper is opened and is return, and new noil must be discharged from the combing device by detaching roller 104.In this stage, the fiber that draws forward by detaching roller is with further combing of so-called top comb (expression among Fig. 9).Simultaneously, nipper is got back to the original position that shows among Fig. 9 and is closed up, and clamps the new fiber palpus of the giving clump that feeds by giving cotton roller 110.Should be readily appreciated that this action is discontinuous at all, therefore giving cotton roller 110 only is to move off and on.

The lap for the treatment of combing has certain width, for example 30 centimetres, and be placed on the machine with the form of lap, as in Fig. 9 with the lap 101 of the local expression of dotted line.This lap rests on two and holds on the volume roller, can only see among Fig. 9 that one of them is with 100 expressions, that second is parallel to first and two rollers all rotate, so that debatching lap 101 trends towards feeding to lap towards above-mentioned combing device continuously in some sense.Shown in Fig. 9 and in the feeding system described in our the early stage european patent application No.338300, at first be sent on the guide plate 113 of an approximate horizontal from the cotton layer of lap 101 debatchings, and deliver to the guide plate 114 of an approximate vertical therefrom, lap is delivered to cotton roller 110 and previously mentioned guide plate 66 from guide plate 114.

Guide plate 113 and 114 is in addition hinged with a flexible material sheet at 190 places, and this flexible material sheet is fixed on the corresponding guide plate with clamping plate 201,210 and screw 220,230.The other end of each guide plate is connected in (not shown) on the frame at 115 and 117 places respectively with jockey suitable, that letter is shown.Pivotally connected 115,117 and 190, make guide plate 113 determine that according to the combing action of ubi supra the reciprocating motion of nipper component 60 relative to each other adjusts their position with frame.Though feed the giving and in the combing device, can only process off and on of lap, but provide suitable lap guide support by holding at lap between volume parts (wherein a part represent) and the combing device with 100, might from reel 101 with one slowly speed continuously hello to lap.

As can see from Figure 9, the preceding roller that holds volume roller 100(promptly more close combing device) is arranged on the back of comb unit, makes the stroke that lap leaves will one section level after the roller 100.This moving horizontally by guide plate 113 of lap guides, and till lap arrived to the position above the cotton roller 110, the lap passage was transferred vertically downward by guide plate 114 then.The pattern of this motion (" geometry of machinery ") is not main.Another kind of situation is plotted among Figure 10.

With U.S. Pat 3,479, the embodiment of the term explanation Figure 10 in 699.Therefore, a pair of lap of lap 200 usefulness holds that volume roller 202,204 is being supported and by debatching feeding nipper component, this nipper component comprises nipper plate 206, and groove cooperates the nippers 212 that forms jaw for cotton roller 208 and one with nipper plate 206.After cylinder pin holder 218 combing of fiber by axle 222 transmissions, their separated rollers 214,216 are accepted.As shown in figure 10, nipper component almost be located immediately at hold volume roller 202 below, make lap roughly Jing directly down feed to nipper.

Nipper component is swung in the swing mode around clamp plate pendulum shaft (only using 226 partial illustration).Synchronized movement ground with nipper component between solid line position that storage-pole 224 is shown in the figure and the dotted line position moves around, and absorbs thus because lap 200 is fed continuously and given and give cotton roller 208 intermittently the lap that produced of output is lax.

Be right after hereinafter explanation and will at first relate to the suggestion that makes generally by equipment automatization shown in Figure 9.To introduce the variation that some generally are suitable for other combing system then.

Fig. 1 shows roughly the critical piece corresponding to the combing head of a vertical section in schematic form.The main comb unit of the combing device of this combing head once more with combing cylinder 1, top comb 2, two detaching rollers 3 and comprise nipper plate 4, corresponding to the nipper device of the nippers 5 of pivotally connected nipper plate.The rotating cotton roller 6 of giving is installed in the nipper plate 4, and the cotton layer 7 for the treatment of combing is fed and given to cotton roller.Cotton layer 7 from lap 8 is carried by holding winding apparatus, and the winding apparatus that holds of explanation in this embodiment is made up of two parallel volume rollers 9 and 10 that hold, and lap 8 rests on it.

Cotton layer 7 passage from lap 8 to comb unit 1-5, be provided with a pair of conveying roller, disconnect the device of lap and the first lap end is connected to the device of the second lap end, the first lap end is the lap rear end that arrives the combing element, the second lap end is the lap front end that comes from full volume, will at length explain below.

In illustrative this embodiment, described conveying roller is to be formed by the roller 11 that presses that preceding holds volume roller 9 and be mated.Another kind method is, by with preceding hold conveying roller that volume roller 9 separates cotton layer from lap 8 be provided.This is to carrying roller 9,11 by a controlled transmission device transmission.

In this embodiment, the lap disconnecting apparatus is applicable to after carrying roller 9,11 and tears lap.For this reason, be provided with second pair and carry roller 13,14 after first pair is carried roller 9,11, this second couple carries roller by controlled second transmission device, 15 transmissions.Under the combing machine normal operation, carry roller 9,11 to rotate with identical peripheral speed for two pairs with 13,14.When lap was disconnected or tears, transmission device 12 and 15 controlled (following also will explain) made them with different peripheral speeds and/or rotate two pairs with different directions and carry rollers 9,11 and 13,14, cotton layer 7 is carried between the roller at two pairs torn.Another kind method is that first pair of conveying roller 9,11 stops operating, and carries roller 13,14 to be rotated further for second pair; Or second pair is carried roller 13,14 motionless, carries 9,11 of rollers to rotate with opposite direction for first pair.Lap all is disconnected in both cases.

The device that the first lap end is connected to the second lap end comprise a pair of by transmission device 18 transmissions press roller 16,17, with a guide that movably is connected with one of two lap ends at least.In illustrative this embodiment, guide is a carriage 19, and it is arranged on the upstream of pressing roller 16,17 by the direction of motion of cotton layer 7 and moves, for example, and mat piston and cylinder unit 20 and move.

Fig. 1 is presented at the described combing head under the normal operating state.Cotton layer 7 is carried roller 9 by lap rotation debatching from the lap 8 is fed to comb unit 1-5 by the conveying roller 13,14 and 16,17 that rotates with same peripheral velocity, and by the comb unit combing.But in Fig. 1, cotton layer 7 has moved back from lap 8 in fact fully, at this moment detect by a detector, for example, detect, detect the stroke of end of reel 7a on the bobbin 8a of lap 8 of lap 7 by color the color of different brightness and/or cotton layer 7 and bobbin 8a with a photoelectric tube 21.Certainly, other detector also can be used for this purpose.

Detector 21 passes to control device 22 with a signal, controls transmission device 12,15 and 18 and following other transmission device that will illustrate then, and the replacing of lap is finished automatically.

Control device 22 is drive piston and air cylinder device 23 at first, and they make consequence volume roller 10 to lower swing, as shown in Figure 2.Therefore, the almost empty bobbin 8a power of relying on for support is rolled to frid formula gathering-device 25 along suitable guide plate 24 backward.In this case, Sheng Xia lap launches from bobbin 8a.

Then, control device 22 control transmission device 12(Fig. 1), make and carry roller 9,11 to stop or counter-rotation.Therefore, when lap layer 7 still normally rotates, cotton layer 7 is carried roller 13,14 to tear by second pair, the place of tearing occurs in two pairs and carries between sieve position 9,11 and 13,14, so that new lap rear end 7b is formed on the exactly determined position on the lap layer 7 that arrives comb unit 1-5, as shown in Figure 3.

Carry roller 13,14 and press roller 16,17 for second pair to be rotated further, before the lap rear end of new formation 7b is just in time pressing roller 16,17, stop, as shown in Figure 4.The transmission device 18 that then presses roller 16,17 quits work, and comb unit 1-6(Fig. 1) also quit work simultaneously.

Carry roller 9,11 to stop fully when tearing cotton layer 7 when first pair, the rear end part 7C that cotton layer 7 disconnects still are retained on the described conveying roller 9,11, as shown in Figure 4.Therefore, carry roller 9,11 to carry roller 13,14 to rotate with second pair once more now, rear end part 7C is sent in the vacuum cleaning pipeline 26, rear end part is removed by it with direction forward.Another kind method is that also available another vacuum cleaner pipeline 27 that is arranged on the back of rear end part 7C is removed, and at this moment, carries roller 9,11 to rotate with opposite direction for first pair, till the front end of rear end part 7C falls into vacuum cleaner pipeline 27.But if first pair is carried roller 9,11 to rotate with antipodal direction and tear cotton layer 7, then the front end of rear end part 7C can fall into vacuum cleaner pipeline 27 without difficulty, and does not require further rotation.

Then, consequence volume roller 10 rotates back into its tip position or normal operation position by the promotion of piston and air cylinder device 23.

Then, control device 22 transmission lap transports have only represented to have the support arm 28 of gudgeon 29 among Fig. 5.New lap 8 on this lap transport band ' and it is placed on holds on the volume roller 9 and 10.

Then, carry roller 9,11 and 13,14 to rotate with direction forward.Hold volume roller 9 rotate by thereon lap 8 '.Hold the surperficial air permeable of volume roller 9, for example be porous surface, and a fixing sleeve pipe 9a is set that 9b at an upper portion thereof slots within it.At this moment, in sleeve pipe 9a, produce vacuum, by groove 9b and the air-permeable surface suction air that holds volume roller 9.Therefore, make a fresh start lap 8 ' cotton layer 7 ' front end 7a ' hold volume roller 9 and be subjected to its vacuum domination once arriving.As shown in Figure 5, front end 7a ' must be attached to hold the volume roller 9 circle place.Then, cotton layer 7 ' move down by carrying roller 9,11 and 13,14.

Cotton layer 7 ' front end 7a ' carry roller 13,14 by second pair after, or first pair is carried roller 9,11 to stop second pair at one section preset time after at interval to carry roller 13,14 to carry roller 9,11 to quicken with respect to first pair.The cotton layer 7 of result ' at two pairs is carried between the roller 9,11 and 13,14 and is disconnected, promptly come from lap 8 ' cotton layer 7 ' on the position determined of a smart square rafter on form a new lap front end 7b ', as shown in Figure 6.

Then, the fore-end 7c ' of cotton layer 7 ' disconnection is inhaled in the vacuum cleaner pipeline 26 after carrying roller 13,14 by second pair fully and is removed.

Then, this two couple carries roller 9,11 still to be rotated further with identical peripheral speed with 13,14, and will come from lap 8 ' cotton layer 7 ' move down.When in case new lap front end 7b ' arrives pressing roller 16,17 fronts or pressing position between roller 16,17 and the guider 19 shown in Fig. 7 approximately, control device 22 drive pistons and air cylinder device 20, guider 19 is moved to the left facing to pressing roller 16,17, as shown in Figure 8.Under these conditions, guider 19 contacts with lap front end 7b ' and it is placed on and still is clamped in the jaw that presses roller 16,17 and from the rear end 7b of the cotton layer 7 that wherein stretches out, rests on down partly on the surface of pressing roller 17.

The transmission device that is used to press the transmission device 18 of roller 16,17 and be used for comb unit 1-6 is simultaneously then connected once more.The rear end 7b of cotton layer 7 and rely on thereon cotton layer 7 ' front end 7b ' be drawn into together and press roller 16,17, this is pressed on two end 7b and 7b ' together roller, and they are coupled together.In this case, guider 19 retracts the right side once more by piston and air cylinder device.Combing head recovers operate as normal then.

Fig. 8 has also represented gathering-device 25, empty bobbin 8a position thereon, it lifts to upper position by the transmission device 30 of piston and cylinder form.On this upper position, empty bobbin 8a and bobbin carrier 28,29(Fig. 5) be connected and be removed, gathering-device 25 is reduced to its original position once more subsequently, as shown in Figure 1.

Above-mentioned combing head can be configured in the form of one group of combing head in the combing machine, wherein the comb unit 1-5 of all combing heads of this group is provided the transmission device of combination.Then control device 22 is tied all combing heads of this group.By transmission device, the especially transmission device 12,15 of control device 22 control and 18 and piston and air cylinder device 20,23 and 30 with also can be jointly being tied (though common control device on principle also control transmission device separately) preceding holding vacuum device on volume roller 9 and vacuum cleaner pipeline 26 and 27 and bobbin carrier 28,29 with all combing heads of this group.

On the other hand, each combing head of this group has subsidiary detector 21(Fig. 1 separately).In case cotton layer 7 is really from the lap 8 of one of them combing head fully during debatching, subsidiary detector 21 passes to common control device 22 with signal, and then, this control device synchronously carries out the replacing of above-mentioned lap on all combing heads of this group.When lap is changed the operation beginning, on this organizes the Lap bobbin 8a of each combing head, still leave the cotton layer 7 of different length, but be positioned at identical height by carrying on new lap rear end 7b all combing heads that disconnect (tear fracture) cotton layer 7 formation between the roller 9,11 and 13,14 synchronously in this group at two pairs.Similarly, even the new lap 8 that provides by Lap bobbin transport 28,29 ' on lap front end 7a ' be not the same place that accurately is positioned on the circumference, the new front end 7b ' of lap of the new lap 7 ' formation by tear fracture still is positioned at identical height on all combing heads.Therefore, the front end 7b ' of lap without difficulty on all combing heads with identical method with guider 19 or common guider 19 with press roller 16,17 and be connected on the rear end 7b of lap.

With regard to above-mentioned combing head, when changing lap, by two pairs of differential gearings of carrying rollers 9,11 and 13,14, with cotton layer 7 and subsequently cotton layer 7 ' respectively from lap 8 and new lap 8 ' disconnection or tear fracture.But, in the embodiment of some changes, some separators can offer certainly cotton layer 7 and 7 ' disconnection.And be used to disconnect second of purpose and carry roller not have absolute necessity.Can provide other disconnecting apparatus that is suitable for by control device 22 transmissions to replace.

Should relate to tearing of lap or disconnected in first to file.Yet for produce following two kinds of results any one it all be unfavorable, that is:

1. one kind produces a uneven fracture of being with the deep-sawing profile of tooth on lap end to be connected; Or

2. one kind does not almost have fiber to reach in good order the otch (as thin slice with scissor cut) of cutting outside the surface.

The better shape of lap end be fiber must or from a roughly straight baseline stretch out must clump, these fibers must or must preferably stretch out perpendicular to the length of lap by clump.Fiber palpus or palpus clump should be with respect to the normal thickness quilts " attenuate " of lap sheet.In this shape, two ends of handling are near the end of " combing ", and end that should " combing " is connecting by " splicing " on detaching roller on the combing machine usually.Therefore, the splicing of lap action is similar to the splicing of comber web, and this work is usually as at roller 104(Fig. 9) or at roller 214,216(Figure 10) on finish.

Though remove fiber neither directly neither be indirectly undertaken by fibre sheet by clamping force, the end form of this processing is preferably produced by the clamping force (being similar to the clamping force that is applied by hold assembly) that is applied to along straight line on the lap.This clamping force preferably equably along the distribution of lengths of clamping lines, promptly preferably spreads all over the width of lap.

Can obtain ideal results by the clamping between a pair of roller with second pair of roller regional lap is drawn back of clamping claw (descriptions) referring to figs. 1 to 8.Distance between the clamping claw should be a bit larger tham the longest fiber in this assembly at least.This distance can be greater than several centimetres of the longest fibers on the lap.This method forms the end that " two " handled, and promptly leaves the upstream and downstream of " tearing " or " disconnection ", though only use an end, these two ends all are important to forming joint.

By clamping lap along one first line (for example between a pair of nipper), along one second line (as with another to nipper) clamp lap, clamping lines is removed can be obtained a similar result then.Distance between these two clamping lines should satisfy the requirement of having described with respect to the jaw line of drawing rollers.This method also forms two ends of handling.

The end portion treatment form that requires schematically is presented among Figure 15 A and the 15B.Figure 15 A shows the plan view of lap processing end, and Figure 15 B magnification ratio from the side shows identical lap.

In Figure 15 A and 15B, represent that with 250 its width is W by the cotton layer that lap launches, thickness is T.Line N among Figure 15 A represents as jaw or clamping line by 9,11 generations of the roller among Fig. 1.Figure 15 A shows and a kind ofly to arrange preferably, wherein jaw line and the lap length setting that meets at right angles.This jaw line can become another angle that (for example, shown in chain-dotted line among the figure) is set with lap length, but will make method of attachment complicated with effective deviation relation at right angle.But a quality that is not 90 ° angle helps further to reduce in the junction worsens.

In Figure 15 B, represent jaw line N with a pair of arrow N.Shown in Figure 15 B, the lap end is fiber palpus or the fiber palpus clump 252 that stretches out from the jaw line with the attenuate form preferably, the cotton layer in jaw line place have with lap on the roughly the same thickness of cotton layer (for the ease of explaining, the compression that is applied by hold assembly is omitted-and lap " thickness " directly provides according to the ratio of per unit lap length and fiber quality (i.e. " mass ", down with)).

In theory, during ideal between lap both ends (export and enter) connects, the end of attenuate will compensate mutually when superimposed, with obtain a constant thickness (fiber quality of per unit length) feed give clamp assemblies new hello to lap.This point is easy to observe in Figure 15 B, has shown the minimizing gradually on the free end per unit length fiber quality from the jaw line to lap among the figure.

But the consideration among Figure 15 A shows that the connection that obtains absolute ideal on the whole width of lap is practically impossible.Therefore, the variation of the lap end of processing must be controlled within the limit of permission, so that obtain satisfied connection.Absolute limit is provided by the obstruction of combing assembly on the one hand, is provided by a kind of " thin splicing " on the other hand, so that lap is before arriving the combing assembly or rupture on this assembly.

A kind of in order to do " high-quality splicing " handled the length (Figure 15 B) of end and must roughly be scheduled to.The end of a kind of " uneven " (representing with chain-dotted line 254 among Figure 15 A) is unfavorable because the most slippery this uneven end will be in relating to connecting moves " cooperation " a kind of identical uneven end on lap.The absolute constant length that guarantees processing lap end on whole lap width W is impossible.This result uses the lines (" fiber ") that stretch out from jaw schematically to represent in Figure 15 A.For example, because this result can appear in the difference of the fibre length of combing on the jaw line, therefore, during carrying out, action should clamp firmly when disconnecting.

Yet the length of lap end can be subjected to a kind of method affect, and this method forms the end of handling, and is explained as follows referring now to accompanying drawing 16 and 17.

Figure 16 shows disconnection (and end portion treatment) device with two pairs of clamping roller 256,258 forms, still (before disconnecting action) extension continuously between them of lap 250.Distance D between the clamping line that is formed by these two pairs of rollers will be to because of keeping roller 256 static, and rotate roller 258 and produce and exerted one's influence in the lap end with direction shown in the arrow in the roller 258.This distance D should be a bit larger tham the length of waiting to disconnect the longest fiber on the fibre sheet at least.This just can guarantee to be avoided that " clamping ", this " clamping " will cause fibrous fracture or operation is broken down.

But illustrated distance D can not be more a lot of greatly than the longest fiber, because may form other uncontrolled or incomplete in check fibre bundle, cause the uneven end problem of representing among Figure 15 A.Should arrange like this, between clamping roller 256 and 258 in the Extendible flake basically all fibres when roller 256 stops, or be subjected to the fiber that stretches out from roller 256 must control and be maintained fixed, or fully enter in the fiber palpus of pulling out by roller 258.Those are at roller 256, the fiber of clamping can not cause and keeps " swimming " (short) fiber will stand drafting force between any problem (as long as they be not clipped in two bites)-bite during disconnecting action in 258 the jaw, but should work as fibre sheet when being drawn back (because " field of force " of on fibre sheet, producing by bite), owing on fibre sheet, keep in control with the frictional constraint of their adjacent fibers.The action of this form provides two suitable processing ends (top and bottom).

In the staple fibre combing machine, the longest fiber on the fibre sheet to be processed generally has and is not more than about 45 millimeters complete development length.Distance D generally should be selected in 60 millimeters to 120 millimeters scopes, and optimum distance is 90 millimeters.The fiber palpus length L that draws like this is within 20 millimeters to 60 millimeters scopes, and preferred length is about 40 millimeters.

Figure 17 illustrates another kind of the arrangement.Fibre sheet 250 is clipped between the nipper 260,262 and (for example, is similar to the nipper of combing device).If fibre sheet 250 extends to the clamping roller (being similar to clamping roller 258) in nipper 260 downstreams (the right), relating to the appropriate consideration at interval of jaw line subsequently is the same with those explanations among Figure 16, and, if the downstream roller is by being similar to nipper 260, second pair of nipper of 262 replaces, and then they will keep identical structure.

The action that disconnects (and carrying out end portion treatment) is finished on the right fiber sheet 250 of nipper 260,262, for example, a straight comb 264 is inserted in the fibre sheet on jaw lines the right, and is clipped in and combs out the fiber palpus on the jaw.For example, such action can be used to prepare to import the end of lap.For the lap end that obtains to control, comb 264 must leave jaw line one segment distance and insert lap, make to remain on the fiber on the fiber palpus or be clipped in jaw, or by with fibre sheet on other fibre restriction control (controlling) by " field of force " that jaw produces.By applying a very strong suction (for example use vaccum suction pipe, schematically illustrate with 266) on the fibre sheet end of stretching out, perhaps can obtain same effect by handling the lap end with the 265 rotation combs of representing with chain-dotted line at nipper 260,262.A kind of like this action only provides one and handles the end.A kind of structure is as shown in figure 17 represented a kind of change type that routine shown in Figure 10 is arranged as basis embodiment illustrated in fig. 11:

As shown in figure 11, in the embodiment of this change, substituted " storage-pole " 224 with a pair of conveying roller 228,230, and one press roller 232(be similar to press roller 11 among Fig. 1) hold 202 combinations of volume roller with lap.Be connected on the negative pressure source 238 by a flexible conduit (schematically illustrating) with 234 vaccum suction pipes that schematically illustrate with 236.This vaccum suction pipe is movably between retracted position (not shown) and progressive position (Figure 11), and the influence of the vacuum that applied by suction pipe on the position of advancing acts directly on roller 202 and presses on the lap below the bite of roller 232.

The action of this device is as follows:

At first driving roller at 228,230 o'clock,, on the output lap, forming one and handle the end, making lap such as top Figure 16 described just by roller 202 with press the jaw line lower end that roller 232 forms and drawn back by stopping the rotation of roller 202;

Such just as already explained, this will provide a upstream process end (on the lap that extends rearward to roller 202) and downstream end (extending on " tail end " of lap length of hold assembly).The downstream tail end just in time remains on the upper end (describing with reference to roller 16,17) of the jaw line of roller 228,230 in Fig. 1.The uninterrupted length that has the lap of handling the end keeps being supported between roller 228,230 and the combing device (giving cotton roller 208 and nipper plate 206) regularly;

Then, the lap that is retained on the old bobbin is removed (for example, as long as it is sent into forward in the vaccum suction pipe 234, vaccum suction pipe has moved on to its operating position as shown in figure 11) by any one suitable device.That is walked empty bobbin and is substituted by new lap, as the explanation of Fig. 5;

Then, on new lap, forming a processing end by new lap being sent into by roller 202 and being pressed in the bite that roller 232 forms, then the lap end of being exposed from bite by 234 pairs in suction pipe applies suction, thus the fiber that some are not held a little or fixedly clamp in the consequent field of force is taken away (as the explanation of Figure 17);

Then, the front end Jing that handled on new lap directly moves down, till it still " passes " roller 228,230 and nipper component and is positioned on the processing end that forms on the previous old lap.In order to do like this, roller 228 preferably is positioned at position shown in dotted lines in Figure 11-therefore there is no need to make the end of handling to move downward transfer from its straight line.If roller 228,230 is positioned at the position shown in the solid line, perhaps the lap end needs from the transfer of its straight line to lower channel, so that new lap end is placed on the end that old lap handled;

Describe as Fig. 1, along rolling up roller 202 to the passage of giving cotton roller 208 from holding, have a few is configured to connection by restarting cotton feeder, in this case, with roller 228,230 superimposed lap end is pressed on together.

Very clear, the roller 232 that presses among Figure 11 can be by leaning against the fixing clamping bar replacement of rolling up on the roller 202 of holding, to form bite.

Structure among Figure 11 and the structure among Fig. 1 are compared, and the following stated merits attention:

Structure among Figure 11 does not require guider (being similar to the guider 19,20 among Fig. 1), because the input lap moves down and carrying its end of handling and place on the end of output lap preparation before.

Structure among Figure 11 does not require the additional roller that is similar to roller 13,14 shown in Figure 1 yet, because end second treatment step (on the input lap) is to finish by the related vacuum plant 234 that forms bite on the volume roller 202 that holding.

The structure of Fig. 1 has two advantages:

The basic structure of machine illustrated in fig. 9 remain unaffected- roller 16,17 is at guide plate 113(Fig. 9) or its equivalent on flatly export lap, and the parts that require to finish the splicing action can be increased to the form of " superstructure " in the existing machine.Certainly, if can consider a new Machinery Design, this point no longer is main.

2. pass through each to roller (16,17; 13,14; 11,9) lap is drawn back the end portion treatment that provides, for example suction pipe 234(Figure 11 mostly than from a vacuum plant) obtain better.

Figure 11 illustrates, and end first treatment step (on the output lap) can be finished by the roller that is used for subsequently the lap end is pressed together (" joint " of Fig. 1 or " pressing " roller 16,17).Therefore, in the structure of Fig. 1, prepare the end of output lap can be by the clamping and the operation roller 16,17 of sieve position 13,14, so that lap is drawn back (comparison diagram 3) between these rollers.Can simplify the operation of the processing end of the bite upper end that is arranged on roller 16,17 like this, so that receive the end of the processing of input lap.But it also may make whole drive system complicated, and this part content is explained subsequently with reference to Figure 18.

Finished after this end first treatment step, it is static that roller 16,17 must keep, and roller extended to the length of the output lap of nipper component so that determine with this.Therefore, this can not participate in second treatment step (on the input lap) of end to roller (" pressing " or " joint " roller).Therefore, if wish in second treatment step of end, lap to be drawn back, must provide a pair of additional roller 13,14 with a pair of roller.In addition, if can not increase the width of machine, this must be positioned at top (as shown in Figure 1) of roller 16,17 to additional roller so, thus, need guider 19,20, so that the input lap that will move down is placed on the end of processing of the output lap of being supported by the roller 16,17 of horizontal feed lap.

According to these suggestions, other the type of being subject to variation of several of structure shown in the figure will be understandable, that is:

At first, if machine can be widened, importing lap so can be from roller 9 horizontal feeding roller 16,17.But the making of lap end can not neither one be specifically designed to this purpose and the mobile device that provides moves in the horizontal direction reliably.The clamp form that Figure 17 shows for example, can form " pendulum pincers " (being similar to the nipper on the combing device).These pendulum pincers move as approximate horizontal, so that the end that will handle links together.This can not be a desirable replacement structure, but it is feasible;

The second, roller 16,17 can be located at guide plate 113,114(Fig. 9) join domain, rather than entering into guide plate 113 parts (as the schematic illustration of Fig. 1).Then, can another clamp be set entering into guide plate 113 places.In this case, also need be on the horizontal channel from the upper end bite to roller the device of the end of the processing of 16,17 " carrying " input lap.

The 3rd, roller 13,14 can be deleted, and uses vaccum suction pipe (being similar to the suction pipe 234 among Figure 11) or comb to come handle clip to be held in by holding volume roller 9 and pressing roller 11(Fig. 1) end of input lap on the bite that forms.

During the normal running, be necessary to carry the place that does not have fixing parts with respect to machine frame actual difficulty (for example, the roller among Figure 11 228) may occur.But, only carrying out lap when action splicing, it is possible moving to the position formation clamp that corresponding to the conveying roller (228) that require splicing signal be connected from a retracted position second roller (230) of a pair of roller.Transmission may be used on second roller, and can pass to by frictional force and carry roller (228), its only supported spool freely rotating around it.

During the normal running, when transmission roller (roller 230) when getting back to its retracted position, carrying roller (228) is freely according to the requirement swing of normal machines action.In case by by the bite that forms between " joint " or " pressing " roller the time, the transmission roller contacts and can disconnect with the transmission of conveying roller in the lap end that connects.

In all embodiment, be desirable to provide one " passage ", by this channel attached end leave press roller after, must deliver to cotton roller (110 among Fig. 9,208 among Figure 10).Should " passage " provide towards the guide surface of two main surface guiding of lap.Suitable passage can be by change guide plate 113,114(Fig. 9) form, for example, the guide plate 313,314 shown in Figure 12." encirclements " of this connection end (local) when they by to cotton roller the time, reduced the danger of join domain disconnection a little less than (relatively) of fibre sheet.

Figure 13 illustrates that a kind of lap holds the change type of winding apparatus.In this case, roller 10(Fig. 1) axis is with respect to the frame fixation of machine, and equipment push rod 300, releases and holds winding apparatus walking empty bobbin 8a.In this case, piston and air cylinder device 23 act on the push rod 300, rather than act in the support of holding volume roller 10.

Figure 14 A, 14B and 14C represent to find out the various variations of lap end scheme respectively.In each case, schematically represented the outermost winding layer of lap on the bobbin.These schemes can be used in and not require to provide and resemble in the situation of porous roller of holding volume roller 9 among Fig. 1.In Figure 14 A, when lap rotated by holding the volume roller, " scraping blade " 302 of a machinery was used for the lap end " is peeled off " from lap.Scraping blade 302 opens on the whole width of lap, and is placed on (as shown in Figure 5) when holding on the winding apparatus when new lap, and its response comes from the signal of control device, moves (for example, by piston and air cylinder device 304) facing to the lap surface.The free edge of scraping blade can indent.

Figure 14 B shows antipriming pipe or jet pipe 304, and it can be used for producing one air flow on the lap surface, to peel off the end of lap.This strand air flow may be by compressed air or by air-breathing generation.Antipriming pipe or jet pipe 304 also can move on to the operating position (from suitable retracted position, not expression among the figure) of finding out the lap end.This antipriming pipe or jet pipe extend on the whole width of lap.

Figure 14 C demonstration has the radially roller 306 of brad 308, and these brads can be peeled off the end of lap facing to the outer surface of lap.Roller 306 also can be as being supported by a rocking arm (not shown), so that move between retracted position (not shown) and described operating position.At operating position, this roller can rotate around its longitudinal axis.Roller 306 also extends on the whole width of lap.

Figure 18 schematically shows a transmission system that is applicable to structure shown in Fig. 1.In this structure, descend to press or engage the combing machine transmission system transmission of roller 17 according to standard, roller 17 replacement laps hold volume roller 100(Fig. 9 in this respect), generally be included into the combing machine transmission system and hold the volume roller.Therefore, the action of roller 17 directly is connected with the action of combing device by the comber controlling system of standard.

Provide a servicing unit to the optional feature that is included in the splicing action now, that is:

Comprise and hold volume roller 9,10(and press roller 11 together) hold winding apparatus and conveying or end portion treatment roller 13,14.

For example be provided with the first stand-by motor 340(, in the machine termination) and be connected with gear 344 by suitable transmission device (for example, cog belt 342), gear 344 is connected with 10 with roller 9 respectively.Jockey pulley 346 can be set to keep the tension force of belt.

The second stand-by motor 348(is set for example, also is located at the termination of machine), for example, be connected with gear 352 by cog belt, gear 352 is connected with the bottom roll 14 of roller 13,14. Roller 14,17 can be used as " roller " that extend along the total length of machine and forms (promptly being connected with all combing head in a side of machine).

Drive mechanism among Figure 18 is a kind of arrangement preferably, wherein, end portion treatment realizes by means of servicing unit (acting on roller 9,11 and 13,14), and connecting moves (being finished by roller 16,17) is included in the machine transmission system of standard, promptly connects transmission combing device with transmission device.

Roller 11,13 and 16 preferably forms as pressing roller, and promptly they are directly by transmission, but the longitudinal axis that is mounted to around them freely rotates.For each combing head this roller that presses of one cover can be arranged, these rollers do not extend on the length of entire machine, but interrelate with each combing head.Complete three press roller 11,13 and 16 and can be installed on the common support frame 354, and support frame pivotally is installed in (not shown) on the framework of machine, for example is installed on the pivot 356.Therefore, support frame 354 can be around the upwards swing of pivot 356 of installing, and will press roller and remove and can utilize the movable passageway of lap to be the combing head service from their transmission roller.

Consult Figure 19 and 20, wherein caption numeral is respectively schemed identical parts with the front and is represented same parts.This combing machine has the pair of engaging roller promptly to press roller 16,17, and a pair of conveying roller is an end portion treatment roller 13,14, and also has a pair of conveying roller 11,9, and one of them roller double as lap again holds the volume roller.Another lap holds volume roller 10, as shown in the figure.Whole transmission device as shown in figure 18, it comprises that a transmission holds the volume motor 340 of roller 9,10 and the motor 348 of drive transfer roller 14.These motors all are subordinated to the main motor of combing machine, as 360 among the figure.Motor 360 not only transmission combing mechanism (not drawing among Figure 19) but also transmission presses roller 16,17.Be transported in the process of pressing roller 16,17 at power and comprise impulse generator 362.This generator 362 signals to central control system 364, thereby guarantees (in machine normal operation process) stand-by motor 340,348 and 360 run-in synchronisms of combing machine master motor where necessary.

What Figure 19 represented is transmission device and the control system that is combined into integral body.As shown in figure 18, roller 17,14,9 and the 10 combing drive line arrangements along combing head (are like this in single-side machine; In two-sided machine, then arrange along the combing drive line of a side combing head wherein at least).And Figure 20 represents is the sensor that links separately with each combing head.Two this sensors are all arranged on each combing head; First sensor 366 be used to detect be placed in hold the volume roller 9,10 bobbin 8a on have or not lap; Second sensor 368 is used to detect between roller 13,14 and 16,17 and has or not lap to pass through.

The operation principle of this system can be found out from the sequential chart of Figure 21.Curve A is illustrated in finishes in the required time of joint action the motion change situation of the motor 340 of drive transfer roller 13,14.Curve B is illustrated in the motion conditions that the motor 348 of volume roller 9,10 is held in transmission in the identical time interval.Curve C is illustrated in the motion conditions of the motor 360 of transmission combing machine (especially pressing roller 16,17) in the identical time interval.Curve D, E, F and G then represent guider 19,20(such as Fig. 1 respectively), piston and air cylinder device 23(such as Fig. 1), negative pressure source 370(Figure 19 of vaccum suction pipe 26) and the motion diagram that acts on the negative pressure source (not drawing among the figure) of porous change device (be in Fig. 1 and 19 porous hold volume roller 9).

At TO constantly, machine is in normal operation, and all motors 340,348,360 all carry out to cotton, combing with a rotating speed that is set by main motor 360.This rotating speed can be set in (as manually) in the machine by control system 364.Output signal by generator 362 and send to the relevant controlling signal of motor 340,348 by control system 364 makes motor 340,348 and motor 360 run-in synchronisms.Other parts described in Figure 21 are failure to actuate constantly at TO.

At T1 constantly, some sensors (as Figure 20) detect the end of the lap on the combing head in the sensor 366, and send corresponding signal to central control system 364.Control system 364 immediate cancel motors 340,348 and 360 run-in synchronism, and directly control each rotating speed of motor.Through of short duration time-delay, control system 364 stops the rotation of motor 340, holds volume roller 9,10 and also just stops operating.And motor 348,360 still turns round, and the result makes the lap between the conveying roller 13,14 that is in static roller 9,11 and rotation be torn.

After one section predetermined delay time t, control system 364 stops the rotation of main motor 360, and whole combing head especially presses 16,17 of rollers and stops operating.Delay time t can suitably adjust, to guarantee by the lap end of pulling apart the processing that action produced with respect to the correct location of pressing roller 16,17, so that splicing action next time.

At T3 constantly, control system 364 is reset motor 340, makes to hold 9,10 rotations of volume roller, shown in curve A, B among Figure 21. Hold volume roller 9,10 and carry roller 13,14 just to be accelerated to a high rotational speed (rated speed that is higher than these rollers), the lap head is removed rapidly by vaccum suction pipe 26.Suction system itself is preferably in and holds the moment that volume roller 9,10 stops for the first time and just stored up energy in advance.

Motor 340,348 rotates, and the lap head is delivered in the vaccum suction pipe 26 continuously, until all the sensors 368(such as Figure 20) all send signal to control system 364, do not show when in detecting area, having lap to exist just to stop.Therefore control system 364 must be noted the state of each sensor 368, detects and has lap to exist in the combing head and when sending proper signal, control system 364 just can enter the next step of splicing action receiving last sensor 368 like this.When detecting the tail end of last lap, control system 364 is closed the motor 340 that volume roller 9,10 is held in transmission when (in the T4 moment), makes to carry roller 13,14 to be decelerated to normal running speed.

It then is of short duration blanking time.Piston and cylinder 23(such as Fig. 1 during this period) start working (seeing F among Figure 21), release bare bobbin 8a, new lap is placed in holds on the volume roller 9,10.This replace tubes action is not drawn in Figure 21, although this is because this action is that the motion of this new lap will be determined separately by a transport control system by control system of machine 364 controls.In interval, new lap is laid by induction system and is put in place during this time, and combing machine itself is not worked.But because blanking time is very short, the motion of drive transfer roller 13,14 still continues.

At T5 constantly, induction system is sent signal to control system 364, shows that new lap is being placed in the holding on the volume roller 9,10 of each combing head under the control of system 364.Like this control system again transmission hold the volume roller 9,10, and make change mechanism by the front respectively scheme described mode begin the action.Just need porous roller 9 is vacuumized (as curve G among Figure 21) for this reason, the motor 340 of transmission roller 9,10 still turns round, send signal until last sensor that constantly links at T6, show when in detecting area, having new lap to exist just to stop with control system 364.This combing machine just is ready for second step of end portion treatment like this.

At T6 constantly, control system 364 is disable motor 340 once more, and carries roller 13,14 to remain in operation.Like this, new lap just is torn between roller 13,14 and roller 9,11, and breaking portion is drawn by still in running order suction system 26 immediately.Thereby second step of end portion treatment has just been finished.Must be fed forward the new lap end of handling this moment, presses the old lap end that roller 16,17 handled and be stitched together so that make them and formerly be positioned at.

One section predetermined, enough carry out the end portion treatment time-delay of (comprise and remove loose wool) after (not drawing especially among the figure), T7 constantly motor 340 reset, the lap end of handling well is fed forward to pressing roller 16,17.Probably in the identical moment, guider 19,20(are as Fig. 1) motion shown in Figure 21 curve D.(specifically do not draw among Figure 21) afterwards through one section time-delay (can select to regulate), at T8 constantly, control system 364 stops the running of motor 340 and 348, thereby stops to carry new lap, and new lap end and old lap end correctly are superimposed together.In this stage, adjust delay time and can guarantee that two ends of handling well can correctly splice.

Through a utmost point short time delay, guarantee that motor stops after, combing machine motor 360 is reset constantly at T9.At the same time, the signal generator 362 by control system 364 makes between the stand-by motor 340,348 sets up synchronous contact again, like this motor 340,348 again with 360 run-in synchronisms again of combing machine master motor.Therefore all motors all accelerate to permanent speed synchronously, and till keeping this motion state some sensors (Figure 20) in sensor 366 to begin to start when splicing is moved next time.

Setting up the while that runs well, piston and air cylinder device 23(such as Fig. 1) get back to its state of shrinking back, purpose is to make machine be in predetermined a certain state, to prepare splicing action next time.But, the sequential of this stage action is unimportant, because guider 19 does not influence regular event.Stretch out when entering the operating position at guider 19,364 of control systems are closed suction system 26.

More than explained the sequential of carrying out various different motion steps among Figure 21 and controlling the appropriate authority of the lap end motion of handling with the mode of sequential.But, adopt distance that pulse signal represents the lap end motion handled to substitute the parameter of time as this lap end motion of control, may be more better.For example, the lap end (old lap) of first treated mistake, the pulse that can utilize signal generator 362 to send is controlled this lap end in the position of pressing roller 16,17 places.After lap was torn, combing machine master motor 360 still rotated, and just stops after control device 364 counts predetermined umber of pulse.Utilize this device, might avoid this lap end position to be subjected to the influence of combing machine rotating speed.Because when realizing that with delay time t optimization is set, will produce this problem.Second can omit lap end location and adjustable timing action (between T7～T8), for example can be by on stand-by motor 340,348, adopting stepper motor, and under the control of control device 364, produce working pulse and achieve the goal.

Basic structure and the operating procedure of the improvement embodiment of the splicing apparatus of combing machine in Figure 22～27 key diagrams 1.Especially the device shown in Figure 22～27 is to prepare to use with the lap passage.Passage 380 is " going down on one's knees " shape, by a pair of guide plate 113,114(Fig. 9) form.Device shown in Figure 22 comprises that a pair of lap holds volume roller 382,384 and a pair of roller 386,388 that presses.Pressing roller is again the feed end that is in the horizontal channel of " going down on one's knees " passage 380.

This device also comprises auxiliary guide plate 381, makes to enter combing device (not drawing Figure 22～27) and can partly fit for the lap of cotton roller (not drawing among the figure) at least with this guide plate from pressing roller 386,388.

In addition, this device also has a suction pipe 390.This suction pipe links to each other by tracheae (not drawing among the figure) and negative pressure source (figure does not draw), it preceding hold roll up roller 382 to press lap mobile between the roller 386,388 below., (as shown in figure 22) in normal operation, hold between volume roller 382 and the roller 386,388 lap 385 with between the suction pipe 390 by 392 isolation of a guide plate.The detailed structure view of the guide plate 392 through amplifying is shown in Figure 22 A.

Shown in Figure 22 A, the guiding utmost point 392 1 ends to be pivotally being installed in an edge that holds volume roller 382 the most close, and on the pivot 394 that parallels with it.Piston and air cylinder device 396 just are installed between frame (letter is shown in 398 places) and the guide plate 392, promote guide plate 392 by it, or in running order, the solid line position shown in Figure 22 A; Or be in the state of shrinking back, the dotted line position shown in Figure 22 A.When being in one position, back, hold the top that the lap of rolling up between roller 382 and the roller 386,388 just is exposed to suction pipe 390.

Suction pipe 390 is also just like the special construction shown in Figure 22 A.Comprise fixation wall 400 in the mouth shape section of suction pipe, suction nozzle lip 402 is arranged on it; And removable wall 404, it can rotate around axle 406, and in its outer end suction nozzle lip 408 is arranged.By suitable operating mechanism 410, removable wall 404 can rotate around axle 406, makes suction nozzle lip 408 be toward or away from suction nozzle lip 402, thereby forms an expansible, folded clamping jaw in the end of suction pipe.Other adjustable controlling organization (figure does not show) also can be set make whole suction pipe 390 with respect to other component movement of diagram, this will can see clearlyer among the figure afterwards.

When receive signal (sending) from some combing heads as sensor 366 from Figure 20,21, show when lap is about to use up that the motor of transmission roller 386,388 stops operating, and transmission hold the volume roller 382,384 motor be rotated further.Guide plate 392 just turns to advanced position (Figure 23) from its normal position (as Figure 22), and the lap between roller 382 and 386,388 just forms round 412, is inhaled in the vaccum suction pipe 390.At this moment, the wall of suction pipe 390 404 just rotates, and makes the mouth of suction pipe freely suck the lap of bilayer thickness.

Suck the cotton circle of sufficient lengths at suction pipe 390 after, the motor that volume roller 382,384 is held in transmission shuts down, and removable wall 404 rotates and makes suction nozzle lip 408 rely on suction nozzle lip 402, is clamp position, and suction pipe 390 arrow D direction in Figure 24 is left roller 388,382.Cotton circle length certain in suction pipe in jaw 402,408 clampings, therefore is in roller 386,388 and just is torn to the lap between the combing head (figure does not show), has also pulled apart the lap that is in roller 382 back remainders simultaneously.The contrast previous drawings is observed above-mentioned state and can be found out, adopts this method to handle effectively still to be in the end 413 of lap before the combing device.Suction pipe 390 also can be used for absorbing the loose wool of the lap end that is gripped by roller 386,388 except being used for pulling apart by the lap of roller 386,388, thereby forms the end of handling well so that splice.By the mutual appropriate size of alternative pack, just can avoid the end 413 of handling with respect to pressing necessity that roller 386,388 is reorientated.

The mouth of suction pipe 390 now opens again, and loose wool is removed from jaw 402,408.Any lap head 415 that holds on the volume roller 382 that covers is also absorbed by suction pipe 390 because of the cotton of giving again of holding volume roller 382,384.

Another kind of preferred the arrangement is that round lap (bilayer thickness) constantly sucks in the suction pipe 390, till each layer lap on the bobbin 414 all is removed.Therefore, when jaw 402,408 is closed, it can only clamping suction pipe 390 and roller 386,388 between the individual layer lap.Then form the lap end of handling simultaneously as above-mentioned this part lap of mode tear fracture.According to this arrangement, only be to remove the lap head after end portion treatment, obviously do not need to restart and hold volume roller 382,384 because loose wool the processing stage be removed.Whether sensor 381 is detectable goes out the lap head and is removed fully, and its detection range comprises holds volume roller 382.

Release bare bobbin 414(Figure 22～24 as previously mentioned) change new lap 417(such as Figure 25～27).Therefore suction pipe 390 is just rolled up roller 382 and is pressed space ascending motion between the roller 386,388 to drawing the position, in 412 suction lines of new lap end by holding.In this position, suction pipe 390 can with other change parts (shown in preceding relevant accompanying drawing) interoperation.Towards the direction of suction pipe 390 right sensors (figure does not show) can be installed along bobbin and survey whether residual lap is arranged on the bobbin, thereby can successfully carry out change.When the clamping device that is positioned at suction pipe 390 mouths was clamped the lap termination of finding, the motor stall again of volume roller 382,384 was held in transmission.Suction pipe is just from holding volume roller 382 and roller 386,388(such as Figure 26) between withdraw.In this process, new lap just is torn above jaw 402,408, and the termination 413 of new lap front end 416 old laps ready and that formerly handled together is stitched together.

Device 396(Figure 22 A) this moment of action again makes guide plate 392 get back to normal operating position (Figure 27).The new lap front end of handling 416 is just located in position, so that superimposed with the old lap end 413 of handling.At this moment, jaw 402,408 unclamps, and loose wool just is sucked system and absorbs, and closes suction system subsequently.

Then, hold volume roller 382,384 and rotate again, treated new lap front end 416 is delivered in the jaw of roller 386,388.Simultaneously, roller 386,388 starts again, the lap end of two treated mistakes is superimposed together in the nip points of pressing roller, and is tightly pressed together.After this lap that is stitched together enters the combing device along normal channel by " going down on one's knees " passage 380, and the relevant accompanying drawing in this point front is described.

Figure 28 is the modifying device of Figure 22～27.In device shown in Figure 28, press roller 386,388 and be mounted in " going down on one's knees " passage 380 places, the lap that leaves these rollers so directly moves downward and enters combing device (figure does not show).The other parts of this device are identical with Figure 22～27.But in this case, bottom roll 388 needs to swing, and and combing device synchronous working.Therefore, only preferably bottom roll is changed into and to rely on the pressure roller that contact with top roller 386 and roll, this top roller 386 can break away from after finishing and the contacting of pressure roller 388 splicing to move.

Figure 29 is the improvement structure chart that makes guide plate 392 motions among Figure 22 A.Improve in the structure at this, guide plate 392 is can be supported around the lever 391,393 of same fulcrum 395 swings by a pair of, and towards " the place ahead " swing of pressing roller 386,388.This guide plate 392 can enter the primary importance (shown in the solid line) of pressing roller to swing between the second place (shown in the dotted line) at the guiding lap around this fulcrum.At second place place, suction pipe 390 clampings by holding and are rolled up the lap end that roller 382,384 transports, and move to change position shown in Figure 25.When guide plate 392 was rocked to the operating position backward and is primary importance, the front end of guide plate was very near pressing roller 388, made on the old lap end that new lap end can superimposedly steadily formerly handle.

The further possibility that lap forms the lap end of handling is pulled apart in Figure 30～32 explanations.In this mechanism, press roller 440,442 and form static jaw, when holding 444,446 reversings of volume roller when pulling apart lap, this jaw just clamps lap.Roller 440,442 also available a pair of clamps replace in this example, and this clamp just in time was closed before the end portion treatment operation.Hold volume roller 444 before 447 at treated cotton end is in and press on the guide plate 443 between the roller 440,442.

Be positioned at the weight of holding bare bobbin 448 on the volume roller 444,446, be not enough to the reversing of roller 444,446 is transferred to lap effectively, thereby can not guarantee the lap rollback, lap is pulled apart above roller 440,442.Like this, a pressure apparatus is installed preferably, bare bobbin 448 is pressed in downwards on the roller 444,446, bare bobbin itself can rotate around the axis of self.Like this, bobbin 448 just and before holds volume roller 444 and forms a jaw 450, when roller 444 reversings, just is enough to cotton is return, thereby realizes desired disconnection action.

Figure 31 shows a kind of more suitable pressure apparatus, and it is made up of pair of support rods 452,454.Every support bar links with pivot with an end of reciprocating connecting rod 456 in reversible piston and the air cylinder device 458.Each root support bar 452,454 all rotates around the fulcrum that is positioned on the support 460 separately.Support 460 is again to be fixed on to be arranged in to hold volume roller 444,446 and a pair of holding on the frame 462 of rolling up between the roller (the only visible roller 464 of Figure 31) the contiguous combing head of lap feeding.Every support bar 452,454 has a rotating pressure roller 466 at its free end.

For example when piston and air cylinder device 458 work, bar 452,454 is just put off-position (shown in the dotted line), no matter is bare bobbin 448 or full packages in this position, and bar 452,454 can not influence contiguous combing head.But when a certain stage, when mechanism was in the splicing duty, just work of device 458 made bar 452,454 put operating position (shown in the solid line).At this moment, each pressure roller 466 all acts on the inner surface of corresponding bare bobbin 448, and with push-tight under the bobbin be pressed onto hold accordingly the volume roller 444,446 and 464 on.Can guarantee bobbin like this and hold volume roller compact ground Contact Transmission, thereby form the bite (figure does not show) of rollback lap head, lap is pulled apart above pressing roller 440,442.Each bobbin 448 all has a continuous pressure roller 466 at its two ends.

Certainly pressure apparatus can act on pressure the outside of bobbin 448, even the new lap of input is positioned on the old bobbin.But, preferably design a mechanism that directly is subjected to combing machine control, its present position does not influence the input lap.

The lap head of pulling apart from old lap is still stayed and is pressed roller 440,442 between the combing device, and they are by a band suction pipe 470(Figure 30) suction system absorb.This suction system then is in the rear portion of holding volume roller 446.For this reason, hold the reversing of volume roller 444,446, forward the mouth of suction pipe 470 to until the lap head of pulling apart, these rollers change and turn to subsequently, make them again by normal feeding direction rotation.When the lap head that is torn returned to the sucker mouth top, the air-flow that suction system produced just made the lap head peel off from bobbin 448, and is inhaled in the suction pipe.After this, bobbin promptly rotates by normal feeding state, till sensor 469 shows that all lap heads have all entered suction pipe.

As device 458(such as Figure 31) work, when withdrawing from pressure roller 466, at first bare bobbin 448 is by release of pressure, then by suitable mechanical device with its release (as previously described).New lap 480(such as Figure 32) just rely on aforesaid transport to be placed on to hold on the volume roller 444,446.The position of new lap 480 must make flee fibre end 482 and consequence volume roller 446 lean on very closely, but must be in " upstream " of normally feeding cotton direction to combing head of holding volume roller 446, promptly as clockwise direction among Figure 32.

Hold volume roller 444,446 now just by normal hello cotton direction rotation, making freely, lap head 482 forwards to gradually because gas main 484 effects still are in suction pipe 470 places of negative pressure.Free lap head is inhaled cotton air-flow and is peeled off lap, and sucks in the suction pipe 470.

Suction pipe 470 is similar with the suction pipe 390 described in Figure 22 A, and it has an expansible, closeable mouth, has a suction nozzle lip 486 to be fixed on the parts 488 on it, and parts 488 link to each other with the suction pipe main body by a flexible belt 490.Piston and air cylinder device 492 are used to open and close suction nozzle, can open the jaw that can close thereby make to form between the tube wall on suction nozzle lip 486 and opposite.

Gas main 484 is to be supported by connecting rod 494, and connecting rod 494 can be rolled up the axis swing of roller 446 around consequence.(this can be surveyed by the sensor that is installed on the suction pipe during by suction pipe 470 stickings when free lap head like this, do not draw among the figure), holding volume roller 444,446 just stops operating, the jaw of suction pipe 470 mouths is closure owing to the action of device 492, and gas main is just swung (shown in figure 32) around roller 446 axle center by counter clockwise direction.Lap " jaw " of formation between lap main body and consequence volume roller 446 that is clamped in the suction pipe 470 located to be torn, and forms the end face of " fiber palpus " or " palpus clump " shape.According to the requirement of Figure 15 A, the described end portion treatment of 15B, new lap is processed into a more suitable end.

Then lap 480 according to rotating (by given volume roller 444,446 rotation directions of holding) for normally cotton direction, holds the below (according to giving cotton direction normally) of volume roller 444 once more before treated lap end is delivered to.Change device (shown in 495 among the figure) is used for the lap end of the new processing mode by aforementioned each figure is stripped down from the lap main body.

The lap end of just having found is dropped on the guide plate 443 with that, the existing old lap end of having handled as described in Figure 30 on it.A mechanical device (figure does not show) can be installed, and it both can be used for new lap end is peeled off from lap, new lap end can be delivered to downwards on the guide plate 443 that has old lap end again.When system reworks, these two the lap ends that are superimposed together can be delivered to again and press in the roller 440,442.Machine carries out normal combing action again subsequently.

As shown in figure 33, bobbin 448 is close to hold see one only among volume roller 464(Figure 33 and hold the volume roller) pressure apparatus a pair of pressure roller 475 is arranged.As shown in the figure, pressure roller 475 be installed in independently be in entopic at the two ends of holding the bobbin 448 of volume on the roller 464.Each pressure roller 475 is all promoted by the piston (can't see among Figure 33) in each piston and the air cylinder device 472 respectively, and pressure roller 475 can be moved back and forth between advanced position (among Figure 33 shown in the solid line) and extended position (among Figure 33 only with shown in the part dotted line).Each pressure roller 475 all can rotate freely around piston rod (show among Figure 33 and draw) separately, with another pressure roller coaxial rotation.Each pressure roller 475 all has a truncated cone 474, and it pushes away face 487 with the circle of bobbin 448 two ends inwalls and just in time coincide.

Shown in Figure 33, hold on the volume roller 464 and all be carved with groove.When pressure roller 475 moves on to extended position, just contact with the taper seat 487 of bobbin 448, force bobbin 448 to move downward to groove roller 464, produce enough frictional drive, like this, pressure roller 475 just rotates with bobbin 448.

Figure 34 is a pair of modifying device that presses roller 440,442.A head is arranged on it, top roller 440 can be moved between with coarctate operating position, lap end and advanced position.In mechanism as shown in the figure, this head comprises that the piston of piston and air cylinder device 489 links to each other with top roller 440, makes the top roller 440 can motion between advanced position (on the figure shown in the solid line) and operating position (only drawing the part dotted line among the figure).When being in the operating position, top roller 440 has just formed a jaw, is used for handling and splicing lap end.After these actions were finished, top roller 440 was promptly return original position.

442 of bottom rolls come transmission by suitable mechanism (not drawing among the figure), can freely rotate around it.When top roller 440 was return, the motor of transmission bottom roll 442 may be closed.At this moment, bottom roll 442 just uses as simple sliver roller.

In the mechanism shown in Figure 32, new lap is inhaled into and is clamped in the suction pipe 470, if roller 444,446 reverses again, then gas main 484 just may no longer need.Certainly, also can both swing gas main 484, make roller 444,446 counter-rotatings simultaneously again, realize the end portion treatment of new lap.

Figure 35 shows that the present invention is applied in another kind of lap processing equipment and is called ribbon lap machine.This ribbon lap machine is the lap that is used for processing the feeding combing machine.Ribbon lap machine is second machine of a pair of combing preparing machine, and this is that lap is made in sliver (sliver) feeding to first machine (sliver lap machines) in the machinery, and second machine (ribbon lap machine) be drawing-off and and close final lap, to be fit to the feeding combing machine.Like this, ribbon lap machine just needs the adapter system of a good energy auto-action, and the details of relevant ribbon lap machine can be consulted the relevant books of Zoltan S.Szaloki work.

As shown in figure 35, traditional ribbon lap machine comprises 444, the 446 essentially identical volume rollers 500,502 that hold among a pair of and Figure 30.Being defeated by ribbon lap machine full volume to be processed (part dotted line 504 only draws among the figure) is wound on the bobbin 506.After lap had moved back, bobbin 506 just dropped on the roller 500,502.

Guide plate 508 normally is arranged in and holds winding apparatus 510 and lap processing unit (plant) 512(is a drafting system at this machine) between.This drafting system has three draw zones, respectively by forming for cotton roller 514, delivery roller 516 and two pairs of middle 518,520 of rollers.The drawing rollers group has cleaning pile loop 522,524 up and down, and they are by deflector roll 526 transmissions.The cleaning pile loop that rotates has condensed the short-term that dissociates out from roller nip.

After leaving drafting system 512, good each web of drawing-off again and send into drawing-off in the contiguous same drafting system after closing again, come out and close web and feed a lap apparatus (not drawing among the figure).This part mechanism and the present invention are irrelevant, just no longer go through here.

Traditional mechanism shown in Figure 35 can carry out following modification according to the present invention, to finish required action:

1. with the lap replace tubes 534(of mechanism among Figure 36 such as the device 23 of Fig. 1 or Figure 13) link together with holding volume roller 500,502;

2. a pair of roller 530(Figure 36 that presses can be set), be similar to roller 386,388 among Figure 22 or the roller 440,442 among Figure 30;

3. be provided with in the top position of pressing roller a lap end portion processing apparatus handle the output lap (this device can adopt the form of the suction system 532 among Figure 36, for example installs 390 among Figure 22 in the end; Perhaps adopt another device to make bare bobbin form the jaw shown in Figure 31,33);

4. the lap end portion processing apparatus also can be set to be handled the end of input lap (this device can be above-mentioned device 532 in thirdly; Also can be end portion processing apparatus independently as the device among Figure 30 470).

The joint process of improved ribbon lap machine like this is similar to the joint process of above-mentioned combing machine, so do not need to be repeated in this description the details of joint process or transmission and control.

Shown in Figure 36 is the modifying device that has optional feature 530,532 and 534, and it also is fully feasible obviously its profile being done to improve widely.
