Abstract
There is a fibre sliver collecting region behind the drawing region of the drafting system on spinning machine. The fibre slivers are carried through said collecting region by an air-permeable conveying belt. Said collecting region is composed of a negative-pressure tank and a sucking slit covered by said conveying belt. Said negative-pressure tank is connected with a traverse driver which is synchronized with the reciprocating traverse unit mounted on drafting system. Its feature is that the fibres are always at same initial position of sucking slit.
Description
The present invention relates to one on the fine spining machine drawing-off and the device of collecting one ribbon, and draw zone back in drafting system settles a set district, one ventilative be placed in the air-breathing line of rabbet joint on the negative pressure trough and one that transport that the conveyer belt of ribbon by the set district, one betransported in the set district that band covers to be installed in and to make ribbon transverse to the reciprocating traversing gear of its throughput direction on the drafting system.
The prior art of this device can be learnt from DE 44 26 278 A1 patents.Because the air-breathing line of rabbet joint is positioned at the negative pressure trough of a fixed in position, the horizontal transporting direction reciprocating motion of ribbon facing to him, ribbon arrives the air-breathing line of rabbet joint not always a same position.Hold and get in order to make the ribbon that traverses to be entirely the air-breathing line of rabbet joint, it is wideer than the width of the stroke that traverses that the spy is provided with the air-breathing line of rabbet joint beginning, the ribbon that traverses so no longer misses the air-breathing line of rabbet joint that arrives fixed in position, but ribbon still can arrive the diverse location of the air-breathing line of rabbet joint, so the size of set is along with infeed stroke change periodically.In addition, the initial air-breathing line of rabbet joint of widening has the shortcoming of higher air consumption.
Task of the present invention is, guarantees that under the situation that does not increase air consumption, the ribbon that traverses arrives the same position of air-breathing groove all the time, and the quality of yarn can not fluctuate because of the transverse movement of ribbon.
The solution of this task is, negative pressure trough is connected to a transverse transmission mechanism with traversing gear synchronous operation.
Based on feature of the present invention, the ribbon of drawing-off accurately reaches the original position of the air-breathing line of rabbet joint in set district all the time in the draw zone, even the air-breathing line of rabbet joint of starting point is narrower slightly.All fibres can be gathered with same intensity in the same manner like this.
Though recognize from Fig. 7 of DE 198 46 268 A1, negative pressure trough with the air-breathing line of rabbet joint is that the conveyer belt with horizontal a ribbon transporting direction carries out transverse movement jointly, and this moment, ribbon did not participate in this transverse movement.But move by the horizontal of negative pressure trough, make ribbon straight, thereby strengthened gathering in the exhibition of air-breathing line of rabbet joint place.
Though traversing gear is not depended in the transmission of traversing of negative pressure trough substantially, must be subjected to Synchronization Control with traversing gear.Yet design of the present invention is that negative pressure trough is to be connected with a traverse bar of traversing gear by a connector.Like this, by simple mechanical connection, can obtain the traverse motion absolute synchronization of negative pressure trough and traversing gear.
In addition, conveyer belt also is to be connected to transverse transmission mechanism.For example conveyer belt is designed to the conveyer belt form, and its slide-and-guide on a sliding surface of negative pressure trough is more favourable.
Because negative pressure trough and traversing gear synchronization traversing can keep 6 to 10 millimeters strokes that traverse that generally adopted at ring throstle so far fully.
Other advantages of the present invention and feature can be understood from following examples of implementation explanation.
The partial cross section side view in a following set of drafting system band of Fig. 1 district, wherein several assemblies of traversing gear have omitted.
Fig. 2 dispenses the roller of the drafting system that pressurizes rocking arm and install on it according to a vertical view of the direction of arrow of Fig. 1 among the figure.
Device according to Fig. 1 of the present invention and Fig. 2 is the particularly part of a ring throstle of fine spining machine, is used for the spinning ingot of each adjacent installation.
Illustrated drafting system 1 can also can be provided with for two adjacent spinning ingots jointly by each ingot that spins.Well-known three roller drafting device structures, it comprise a rear roller to apron roller in the middle of 2, right and front roller to 4.The coordination roller preferably is connected with the roller line segment of driven perforation machine length to 2,3 and 4 bottom roll 5,6,7.Always be disposed at a spinning ingot with the roller 8,9 and 10 of bottom roll 5,6 and 7 coordinations and under the needs situation, connect into so-called pair of roller with adjacent roller.The apron roller generally disposes a following apron 11 and upper leather ring 12 and at the hypodermis volume a so-called guide plate platform 13 is installed 3.
Usually roller 8,9 and 10 is clamped on the pressurization beam 14 and the bottom roll 5,6 and 7 under flexibly being pressurized to.
An one ribbon or rove 15 that dotted line is represented are drawing to desired number by throughput direction A usually in drafting system 1.The draw zone 17 of drafting system 1 is to terminate in front roller to 4 one output jaw line 16.
An input collector 18 is placed in rear roller to before, and the apron roller in the middle of a collector 19 that is installed in the front draft zone is configured in is to being configured in front roller to before 4 with a collector 20 that is placed in main drawing area before 3.These collectors 18,19 and 20 purposes are that ribbon or rove 15 carry out the side when drawing-off assembles.This is not enough in common mode, because formed a so-called spinning triangle in the back of output jaw line 16, if obtain immediately under the situation of its spinning twist at the ribbon 22 of drawing-off, this triangle can play ill-effect to the quality of yarn.That is to say that the spinning triangle has the edge fiber of together not twisted fully in spun yarn, therefore the powerful reality to yarn does not play effect.
In order to remedy this shortcoming, made such layout in the recent period, a so-called set district 21 is set after drafting system 1, in this zone through the ribbon that dots 22 of the no twist still of drawing-off, by the avris cohesion of its edge fiber and boundling or set.Be no longer to form the spinning triangle on the output jaw line 30 of boundary with the outlet side in 21 back, set district, therefore the brute force and the uniformity of the yarn 31 that forms are better, seldom filoplume.
The ribbon 22 that should gather is to be carried by the set district by a ventilative conveyer belt 23.Conveyer belt 23 can be designed to as illustrated in fig. 1 and 2 such as a thin fine mesh fabric band.Conveyer belt 23 slips over the exterior contour that is designed to hollow profile and is stretched over the negative pressure trough 24 of a machine sections.Conveyer belt 23 leaves negative pressure trough 24 and through a tension element 25 in this side in set district 21 dorsad.Tension element is so to be provided with, and makes conveyer belt 23 touch bottom roll 7, at this moment conveyer belt 23 and the mutual reverse movement of bottom roll.Like this, the fiber flyings that may adhere on the conveyer belt 23 are cleaned continuously.
The outlet side in set district 21 is to grip roller 29 by one to delimit, and this roller also is to be clamped on the pressurized cradle 14.Its transmission conveyer belt 23 is also playing one aspect the twisting in spinning jointly with negative pressure trough 24 and is ending the sth. made by twisting effect.
Above-mentioned collector 18,19 all is connected with traversing gear 32 with 20, traversing gear make collector 18,19 and 20 and make ribbon or rove 15 and the ribbon 22 that should gather transverse to transporting direction A about 6 to the 10 millimeters stroke that traverses that traverses.This main purpose of traversing is to prevent the upper leather ring 12 of drafting system 1 and the front roller too quick-wearing to 4 roller 10.Transverse movement is to be connected not traverse bar 33 acquisitions of the transmission mechanism of expression on the figure by one, and traverse bar directly is connected and is connected with 20 by the collector 19 of the leaf spring shown in Fig. 2 34 with other with input collector 18.Whole like this collector 18,19 and 20 is according to direction C and the D reciprocating motion of traversing.
If drafting system 1 has disposed common aggregate device 21, then danger can appear, promptly leave the air-breathing line of rabbet joint 27 original positions of the ribbon 22 inaccurate arrival draw zones 21 of output jaw line 16.Should admit fiber in identical position all the time, because can only all fibres be gathered under same way as.Therefore according to arrangement of the present invention, negative pressure trough 24 also participates in the reciprocating motion of traversing gear 32.For this reason, negative pressure trough 24 can move and is connected with traverse bar 33 in the case in the avris direction.So negative pressure trough 24 also participates in reciprocating motion according to traverse direction E and F.
The connector 36 that negative pressure trough 24 is linked to each other with traversing gear 32 is to be made of two longitudinal beams that are arranged on pressurization beam 14 1 sides and the bottom roll 5,6,7 as the connector 36 that horizontal transmission mechanism 35 uses for negative pressure trough 24.
If by the above embodiments, conveyer belt 23 is designed to slip over the conveyer belt of negative pressure trough 24, is necessary that then conveyer belt 23 traverses together with negative pressure trough.For this reason, at negative pressure trough 24 next doors configuration corresponding synchronous block 38 and 39, its spacing is equivalent to the width of conveyer belt, and block is in the avris guiding and participate in traverse motion.
