Description
Technical field
The present invention relates to a kind of device that is used for compacting fiber strand on spinning machine, it has the delivery roller that the is located at drafting system compacting zone to the back; Having one is used for the conveyer belt of fiber strip conveying by the gas permeability of compacting zone; Have one in set compacting zone the conveyer belt guiding suction channel on a sliding surface; Has a suction slit that is arranged on this sliding surface; Have that an end in compacting zone is pressed on fiber strip on this conveyer belt and conveyer belt is pressed on nip rolls on the sliding surface; And have one drive conveyer belt, by comprising a driven fluted roll and the friction gearing that roller guided that is pressed in the delivery roller centering of the pressure roller above it.
Background technology
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.
The device of the first described class of literary composition has proved in the employed different compacting zone of compacting fiber strand effectively, and such device can obtain from DE 199 11333 A1 and DE 198 37 181 A1.In these two kinds of devices, the conveyer belt of gas permeability is by the delivery roller by drafting system a friction gearing that is guided to be driven.
In the device according to DE 199 11 333 A1, nip rolls is used as the driving of conveyer belt.This roll itself is that the transmission by the right pressure roller of delivery roller brings driving.
Then opposite in according to the device of DE 198 37 181 A1, nip rolls is driven by conveyer belt, and conveyer belt itself is around the right fluted roll of delivery roller of drafting system.
In friction gearing, a friction pair is arranged respectively all not only on the right pressure roller of the delivery roller of drafting system, and on nip rolls according to DE 199 11 333 A1.The right peripheral speed of the speed that it can make conveyer belt and delivery roller is definitely consistent.In the friction gearing according to DE 198 37 181 A1, though the driving of conveyer belt transmits speed very accurate owing to the winding of the right fluted roll of delivery roller, this conveyer belt is loaded the clamping pressure with delivery roller.This clamping pressure is because it has limited the main drawing area of drafting system, so compare and will obviously increase with the required driving of conveyer belt.
Summary of the invention
The basis of task of the present invention is to create a kind of friction gearing that be used for conveyer belt of delivery roller to being guided by drafting system, wherein, the speed of conveyer belt is complementary with the right peripheral speed of delivery roller as far as possible exactly, and does not have other unnecessary high clamping pressure and act on the conveyer belt.
This task solves like this, promptly for the right roller of the set delivery roller of friction gearing conveyer belt is pressed on the slidingsurface and to it to drive.
By this structure, the right peripheral speed of delivery roller does not need other to comprise the intermediate gearing of friction and directly is transferred on the driving belt, in addition, conveyer belt not to delivery roller to applying clamping pressure.It may also help in addition: make influence the suction of compacting slit extend to from the driving jaw line of driven roller the restriction compacting zone nip rolls roll a little on.If be additional to the roller of friction gearing is the right pressure roller of delivery roller, then keeps the formation of principle of the effective structure of proof of DE 199 11 333 A1.
Pressure roller with different clamping pressures is positioned on the fluted roll that is added on the one hand, is positioned on the sliding surface on the other hand.Thereby can counter extensioin the required higher clamping pressure of the drawing-off of device and the required desired condition of less clamping pressure of the friction gearing of conveyer belt carried out required calculating.Different high clamping pressures can obtain by the geometry that is carried in the spring in the pressure roller.
Though can realize direct frictional drive according to the present invention, also be additionally provided with nip rolls is driven by pressure roller by an intermediate gearing.Therefore conveyer belt can forward transmission on two positions, is just directly driven or is driven by nip rolls by middle drive unit by a right roller of the delivery roller of drafting system.In middle drive unit, can adopt cog belt transmission or gear drive.
Description of drawings
Other advantage of the present invention and feature can be known from the explanation of an embodiment described below.Accompanying drawing is depicted as:
Fig. 1 represents the partial cross section by the side view of the friction-driven of the device delivery band that is used for compacting of the present invention.
Fig. 2 represents the view on actual compacting zone seen by arrow II among Fig. 1.
The specific embodiment
In Fig. 1 and 2, only represent from the end regions of each spinning drafting system 1 that is provided with of spinning machine, particularly a ring spinner.Can see delivery roller to 2 from drafting system 1 people, and an apron roller that is located at its front is to 3, this roller is to comprising a following apron 4 and a upper leather ring 5.This delivery roller comprises a fluted roll 6 that vertically drives along machine to 2 and is located at pressure roller 7 on each spinning position.
In drafting system 1, an one ribbon or rove 8 are drawn into needed fineness with the method for knowing by throughput direction A.So delivery roller to 2 output jaw line 9 on, the draw zone of drafting system 1 just comes to an end.
Have that a face was provided with drawing-off in output jaw line 9 back but still untwisted fiber strip 10, it will be owing to so-called reason by boundling or compacting, thereby it passes a compacting zone 11 and is connected with drafting system 1, wherein fiber strip 10 becomes thinner by the amalgamation of its fiber side, thereby the twist afterwards in distributing described worrying spinning triangle can not take place again.
The conveying of passing compacting zone 11 for the fiber strip 10 of compacting is to adopt the conveyer belt 12 of a gas permeability to realize.Ribbon 10 remains on the conveyer belt by suction airstream.Therefore conveyer belt 12 preferably includes the webbing of the fine mesh that a kind of thin filament yarn is made into, it is exactly a gas permeability from the beginning, and need not conveyer belt 12 is made porous.
By guiding on a sliding surface 13, this sliding surface 13 is to be made of an exterior contour that extends to the suction channel 14 on a plurality of spinning position to conveyer belt 12 in the scope of compacting zone 11.Suction channel 14 is designed to the profile of hollow, and is in vacuum condition.By vacuum adapter 15 being connected internally on the vacuum source of not representing among the figure that is located on a plurality of spinning position suction channel 14.Have a suction slit 16 on sliding surface 13, some is provided with obliquely slightly for the direction of motion of conveyer belt 12 in this slit, and extends to the end of compacting zone 11.By the suction slit 16 of this slight inclination, in compacting process, can add and carry out slight false twisting fiber strip 10.
A nip rolls 17 is used for yarn twisting away from compacting zone 11, and it makes compacting zone 11 roll a little by one at outlet side and 18 is limited in the cracks extension part of aspirating slit 16.Nip rolls 17 is pressed to conveyer belt 12 to fiber strip 10, simultaneously conveyer belt 12 is pressed on the sliding surface 13.
The yarn 19 that is produced has obtained yarn twisting when rolling a little 18 connections together, this moment, it was directed on outbound course B in the twisting apparatus of not representing among the figure, and for example one is encircled on the ingot.
Therefore roll a little and 18 be used for stopping twisting, can not return in the compacting zone 11 so that yarn is twisted.
Conveyer belt 12 drives by a friction gearing, according to the present invention, it be by delivery roller to a roller of 2, shown in situation under carry out by pressure roller 7.In addition, in being connected the output jaw line 9 of drafting system 1, pressure roller 7 and a jaw line that is called driving jaw line 20 are close on the sliding surface 13, and wherein fiber strip 10 is crushed on the conveyer belt 12, and conveyer belt 12 is crushed on the sliding surface 13 simultaneously.Can be at the clamping pressure that drives on the jaw line 20 significantly less than the clamping pressure on output jaw line 9.Because the direct friction by pressure roller 7 drives, thus delivery roller 2 peripheral speed directly is transferred on the conveyer belt 12, thereby an additional advantage is arranged, promptly aspirate slit 16 and can not only extend to nip rolls 17 places, and can also extend to pressure roller 7 places.
Do not repel to make nip rolls 17 additionally come transmission by drive unit 21 in the middle of according to friction gearing of the present invention, and drive conveyer belt 12 by way of parenthesis by pressure roller 7.This centre drive unit 21 is not to be absolute demand, and it only dots, and can comprise cog belt or gear train.
