Abstract
A drawing unit on a spinning machine follows a compressing zone for compressing a drawn, non-spinning fibre bundle. The compression zone comprises an air-permeable transport belt (12), for transporting the fibre bundle through the compression zone. The transport belt runs on a slide surface (13) of a suction channel (14) and is tensioned by a guide roller (18). A suction slot, running essentially in the transport direction of the fibre bundle is arranged in the slide surface (13). The end of the compression zone is marked by a pinch roller (19) which presses the fibre bundle and the transport belt to the slide surface. The guide roller is arranged in the region of the driven lower roller (7) of the output roller pair (8, 9) on the drawing unit and forms a V groove therewith. An intermediate groove is on both the lower roller and the guide roller in the V groove (29) and thus drives the transport belt.
Description
The present invention relates to a device that on a fine spining machine, is used for compressing fiber assembly, this device have a front draft zone that limits a drafting system, comprise that the output drawing rollers of a driven bottom roll and a drawing-off top roller are right; Have one and be positioned at this front draft zone compacting zone afterwards; Have the conveyer belt of a conveying fiber yarn through the gas permeability of this compacting zone; Have one be located in this compacting zone, with the suction channel of this conveyer belt guiding on a sliding surface; Has a suction slit that is arranged in this sliding surface; Have one and limit gripping roller this compacting zone end, that on this sliding surface, exert pressure; The roller that turns to this conveyer belt of tensioning; And have and be used for driver element this conveyer belt, that cooperate with this bottom roll.
If the delivery roller that the fiber strip of drawing-off is directly connected to drafting system on twist, on the right jaw line of this delivery roller a so-called spinning triangle will appear then.This is because the fiber strip of drawing-off leaves drafting system with a fixing width, and co-twisted becomes a yarn that diameter is less.The spinning triangle has abandoned not enrolling in accordance with regulations the edge fiber in twist yarn, therefore seldom or at all is helpless to the intensity of institute's spun yarn.Therefore recently people transfer to and are provided with one are rolled the so-called compacting zone that a little is limited in outlet side by one behind the draw zone of drafting system, have only after this and could twist yarn.Fiber in compacting zone by boundling or compacting, thereby make fiber strip when leaving last roll, become very thin, and the spinning triangle worried no longer takes place.So the yarn that is spinned will be more all even solid, and fine hair seldom.
In DE199 11 333 A1, a kind of this paper starts the device that is used for compressing fiber assembly of described type and has represented this prior art.In this known devices, the driving of conveyer belt is drawn by the right bottom roll of output drawing rollers through a plurality of friction levels.This bottom roll drives its drawing-off top roller of exerting pressure, and the drawing-off top roller couples together at the gripping roller of the qualification compacting zone of outlet side by a driving belt handle therewith.This grips roller and conveyer belt is pressed on the sliding surface of suction channel, and itself drives this conveyer belt by friction then.
Such shortcoming is arranged in known transmission: promptly being used to make frictional drive to become possible gripping roller must put on conveyer belt with a minimum pressure, and this minimum pressure need be higher than the pressure that is used to twist hold function.In the acting in conjunction of the friction of conveyer belt and sliding surface, this will cause the raising of suction channel wearing and tearing on the position of output jaw line.
Task of the present invention is, this driving that is used for this conveyer belt is by the right bottom roll guiding of output drawing rollers, and will grip the pressure that roller is applied on the sliding surface and adjust to only for twisting the needed size of hold function.
This task solves like this, promptly is provided with on the position of this drawing-off top roller and turns to roller, and constitute a wedge gap with this drawing-off top roller; Roller in the middle of this driver element comprises one, roller is close to bottom roll and turns on the roller in the middle of this in wedge gap.
This conveyer belt no longer drives by rubbing on a position as aforesaid prior art now, promptly on this position, be not directed through a sliding surface, but on this position by the friction-driven clamping between the roller of two rotations or the roller.This turns to roller to be applied in spring pressure towards middle roller herein.Because turning to the direction of motion of roller and middle roller is in the same way, so though on the position that drives transmission, have extra high thrust, the not wearing and tearing of significant.This grips roller and itself is driven by conveyer belt this moment, and only needs to twist on output jaw line and stop required pressure, and at the critical positions place of this jaw line, the wearing and tearing of suction channel have obviously reduced like this.Demand for the power that drives has also reduced simultaneously.
In order to guarantee that conveyer belt carries operation by middle roller, this centre roller is provided with a suitable frictional layer.Roller only is close on the axle collar that turns to the roller avris in the middle of can imagining this, and this conveyer belt is turning to servo-actuated on the roller by angle of contact, but when this conveyer belt was turning to transmission position between roller and the middle roller to be held, this still had advantage.
Because it is suitable giving this conveyer belt certain force of strain drawing-off in compacting zone, so the speed of conveyer belt should be slightly larger than the right peripheral speed of output drawing rollers.For this reason, bottom roll is provided with the axle collar of an enlarged-diameter, and middle roller is close on this axle collar.The axle collar can be a disk that is easy to change hereto, makes the requirement for the accurate coupling of tension draft become possibility like this.
Other advantage of the present invention and feature can be known from the explanation of an embodiment described below.Accompanying drawing is depicted as:
Shown in Figure 1 is by a partial cut away side views according to device of the present invention.
Direction that shown in Figure 2 is, the view of seeing from the driver element of real compacting zone and conveyer belt along arrow II among Fig. 1.
A fine spining machine, especially a ring throstle, with a relation that is used for the device of compressing fiber assembly 1, only show the end regions of a drafting system 2.This drafting system 2 itself only drawn a pair of output drawing rollers to 3 and one be positioned at these output drawing rollers to before apron to 4, this apron is to having a following apron 5 and a upper leather ring 6.These output drawing rollers itself comprise a driven bottom roll 7 and a drawing-off top roller 8 to 3, and drawing-off top roller 8 and bottom roll 7 limit an output jaw line 9.On this output jaw line 9, the front draft zone of drafting system 2 finishes.
A ribbon or a rove 10 become desired fineness along throughput direction A drawing-off in known manner in drafting system 2.A compacting zone 11 is arranged at the output drawing rollers after to 3 junction, this drafted but still untwisted fiber strip 1 is by boundling or compacting therein.
Article one, the conveyer belt 12 that belongs to the gas permeability of compacting zone 11 finishes to be the thin fine mesh webbing that is made into by polyamide yarn.This conveyer belt 12 carries the fiber strip 1 of compacting through this compacting zone 11, and is directed herein through a fixing sliding surface 13.This sliding surface 13 is an appearance profile that is in the suction channel 14 of negative pressure preferably, a plurality of spinning of the best extend past of this suction channel position.This suction channel 14 is connected on the low pressure source of not drawing by a negative pressure tube connector 15.
A suction slit 16 is arranged in this sliding surface 13, and extend generally along throughput direction A in this suction slit, but slightly favour the direction of motion of conveyer belt 12.This suction slit 16 is in traffic direction, side has a so-called meticulous seamed edge 17 within it, and the fiber strip 1 of compacting moves along this seamed edge, and straight by exhibition easily herein simultaneously.
This conveyer belt 12 is except being directed on the sliding surface 13, and it also is directed into one and turns on the roller 18, and this turns to roller 18 and suction slit 16 to be provided with at a certain distance, and this turns to roller 18 extend pasts a plurality of spinning position and this conveyer belt 12 of tensioning.
Be provided with one in compacting zone 11 outlet side ends and grip roller 19, this grips roller and on an output jaw line 20 fiber strip 1 is pressed to sliding surface 13 together with conveyer belt 12, and is driven by conveyer belt 12.Therefore this output jaw line 20 limits compacting zone 11, and simultaneously for subsequently and the effect of the spinning that comes twisting start-stop sth. made by twisting does not turn back in the set district 11 twisting.From exporting the spun yarn 21 that 20 generations of jaw line are spun into, this spun yarn flows to a twisting mechanism that does not illustrate along outbound course B then, for example a ring ingot.
A pressurized cradle 22 belongs to drafting system 2 in known manner, all the other the drawing-off top rollers do not drawn and the gripping roller 19 of these pressurized cradle 22 supporting drawing-off top rollers 8 and drafting system 2.Because the load pressure very inequality of drawing-off top roller 8 and gripping roller 19, the pressue device of pressurized cradle 22 comprises the compression spring spare 23 and the compression spring spare 24 that is used to grip roller 19 that are used for this drawing-off top roller 8.Compression spring spare 23 power of being carried is the manyfold of the power of compression spring 24 herein.
All the other bottom rolls that do not further specified or draw of this driven bottom roll 7 and drafting system 2, vertical setting of pressing fine spining machine in common mode, and be placed in the so-called drawing rollers seat 25, as shown in Figure 2 with favourable interval.This drawing rollers seat 25 also supports suction channel 14 and turns to roller 18.
This turn to roller 18 can be directly installed on according to the present invention bottom roll 7 near, and constitute a wedge gap 29 with this bottom roll 7.Roller 27 in the middle of one is arranged in this wedge gap 29, and it also is supported in the drawing rollers seat 25, and is pressed against bottom roll 7 by spring simultaneously and turns on the roller 18.Roller 27 is driven by bottom roll 7 herein in the middle of this, and it self turns to roller 18 by friction-driven, also drives conveyer belt 12 simultaneously.For this reason, middle roller 27 is provided with one deck friction lining 28.
Especially as can be seen from Figure 1, two members that are synchronized with the movement are arranged on the position of frictional drive, just in the middle of roller 27 and turn to roller 18.For this reason, though be useful on the pressure of necessity of frictional drive, in fact not wearing and tearing.This grips 19 of rollers need apply a power of pressing to sliding surface 13 on the position of this output jaw line 20, guarantee needed twisting hold function by this power, and the current roller that should grip itself is driven by conveyer belt 12.
Make the speed of conveyer belt 12 be slightly larger than the output drawing rollers to 3 peripheral speed in order on this fiber strip 1, to produce a slight tensioning drawing-off, bottom roll 7 is provided with the axle collar of an enlarged-diameter near drawing rollers seat 25, this axle collar for example can constitute by the disk that can change 26.Middle roller 27 be close on this disk 26 and thus disk drive.Because comparing with bottom roll 7, disk 26 has a diameter that has enlarged, so this necessary tensioning drawing-off is applied on the fiber strip 1.
