Background technology
When the fiber skein of drawing-off just obtained spinning twisting in the right back of the delivery roller of drafter in spinning machine, so-called spinning triangle appeared on the right jaw line of delivery roller.This is to leave drafter and become thinner line by twisted because of the drawn fiber strip that certain width is arranged.The spinning triangle comprises the edge fiber, during they are not bundled in accordance with regulations and twist thread, thereby very little to yarn tensile strength less than contribution or contribution.Therefore, in recent years, people transfer a so-called cluster area is arranged in the downstream of the draw zone of this drafter, and the outlet side of this cluster area is the boundary with a jaw line.Yarn only just can obtain spinning twisting in its downstream.In cluster area, fiber is by boundling or set, and thus one, when fiber skein left last jaw line, it is too narrow that fiber skein becomes, so that worrying spinning triangle no longer is a significant disadvantages.The yarn that is spun into is then more level and smooth, firmer and not too brushy.
Know the different beaming device that is used for the boundling fiber skein already, most devices wherein bring work with ventilative conveying, and this conveyer belt makes the fiber skein for the treatment of boundling slide past the top of a suction slot.For example, DE19911333A1 discloses the device of this type.Also described a conveyer belt in the document, it comprises a ventilative mesozone that is formed by the fabric that is made of the thermoplastic silk and an air-locked marginal zone is respectively arranged in both sides.The edge of marginal zone can be reinforced by heating.
Should be noted that at this term " pneumatic boundling " in present patent application also should comprise this device, wherein, except that suction airstream, other means for example also can realize towards the conveying component of the suction slot of tiltedly putting.
Summary of the invention
Task of the present invention is the new conveyer belt that the above-mentioned type is provided for the pneumatic boundling of fiber skein, wherein constitutes these air-locked marginal zones by particular form.According to the present invention, so finish this task, promptly Tou Qi mesozone and these air-locked marginal zones are all made by fabric, and in this fabric, it is airtight by heating these marginal zones to be become.
Although in the conveyer belt of prior art, disclose how to make the marginal zone become air-locked and concerning known conveyer belt by the heating strengthened edge district the edge, but new conveyer belt is based on a kind of fabric that is made of thermoplastic silk public affairs fully, in this fabric, it is airtight by heating whole marginal zone to be become.In other words, ventilative fabric is transformed into level and smooth paillon foil approx on the marginal zone in the mesozone.Therefore, this new conveyer belt has obtained higher shape stability, especially in the time will often will cleaning for cleaning.The dirt that narrower ventilative mesozone has caused being deposited on the conveyer belt reduces, because have only real workspace just to be sucked, thereby fibre down or dirt can not adhere to because of suction.Novel conveyer belt has especially caused longer service life.
Advantageously, conveyer belt is seamless on throughput direction, and this can so accomplish, promptly its is become tubular by cylinder weaving seamlessly.Monofilament is advantageously used in this fabric, and these monofilament have enough stability and allow uniform suction airstream.
It is airtight by heating the marginal zone of conveyer belt to be become according to different modes.Stipulate that in a variant it is airtight by welding these marginal zones to be become, this welding is for example finished with a quite wide electrode.In another embodiment, these marginal zones can scribble hot melt adhesive, wherein, as long as it is just much of that to be coated with gluing on a surface of conveyer belt, thereby still keep braided structure on another surface.
In fact, fact proved that such conveyer belt is favourable, wherein, the width of ventilating area is 0.3-0.5 a times of conveyer belt width.For example, can there be the width of 10mm ventilative mesozone, and the wide altogether 25mm of conveyer belt.Therefore, 7.5mm respectively does for oneself in these air-locked marginal zones.

From following explanation, obtained other advantage of the present invention and feature to some embodiment, wherein:
Fig. 1 cuts open side view with office and represents a fiber skein beaming device, and it has conveyer belt of the present invention;
Fig. 2 has wherein omitted roller shown in Figure 1 to represent real cluster area along the view of Fig. 1 arrow II direction;
Fig. 3 represents according to conveyer belt of the present invention with the cross section zoomed-in view;
Fig. 4 represents another form of implementation of conveyer belt with the cross-sectional view that is similar to Fig. 3.
The specific embodiment
Fig. 1,2 illustrate that spinning machine and especially ring spinner one is used for drawing-off of boundling but the zone of the device 1 of untwisted fiber skein 2.This device 1 is right after in the downstream of drafter 3, the delivery roller that only shows this drafter to 4, a pair of once apron 6 and a upper leather ring 7 and apron roller that be arranged in delivery roller 4 upstreams arranged.Delivery roller comprises that to 4 a driven output bottom roll 8 and one are pressed in that output pressure roller 9 by elasticity.Delivery roller is to jaw line 10 that forms the draw zone end of drafter 3 of 4 definition.
In drafter 3, an one fiber strand or rove 11 are drawing to required fineness according to known way on throughput direction A.Drafting process ends to export jaw line 10 places, and just has drawing-off but still untwisted fiber skein 2 from this some beginning.In order to reduce known disadvantageous spinning triangle, fiber skein 2 is just gathered in cluster area 12 after output jaw line 10.The device of establishing for boundling 1 comprises a ventilative conveyer belt 13, and it makes the fiber skein 2 for the treatment of boundling through cluster area 12.This device 1 further comprises a hollow profile form and suction channel 14 that can spread all over a plurality of spinning points that is configured to be under the negative pressure.In the face of on the outline of cluster area 12, suction channel 14 is configured to a shape that is used to guide the sliding surface 15 of this conveyer belt 13 at it.
Article one, suction slot 16 is positioned at sliding surface 15, and the direction of motion of its relative conveyer belt 13 slightly becomes, thereby one of them side of suction slot 16 is configured to fibre guide limit 17 with treating boundling fiber skein 2 relevantly.During boundling, fiber skein 2 moves along this fibre guide limit 17, and thus one, the fiber in fiber skein 17 is gathered or boundling transverse to the direction of motion ground of conveyer belt 13, and fiber skein 2 is clot slightly thus.
Have the negative pressure of certain distance to take over 18 by one with suction slot 16, suction channel 14 is connected on the unshowned vacuum source.If suction channel 14 spreads all over a plurality of spinning points, then a vacuum pipe 18 is set for 14 of each suction channels.
It is the boundary that the outlet side of cluster area 12 grips roller 19 with one, and this roller is pressed onto fiber skein 2 and conveyer belt 13 on the sliding surface 15, limits an output jaw line 20 that the spinning twisting that will obtain is played the effect of resistance twist part thus.Grip roller 19 driving conveyer belts 20 and itself be output pressure roller 9 and drive by the drive 21 that becomes gear-like.
When on throughput direction B yarn 22 being delivered to a unshowned twisting mechanism as ring during ingot, the yarn of formation has obtained spinning and has twisted after output jaw line 20.Relevant ground with spinning twisting, output jaw line 20 plays the effect of resistance twist part, thereby spinning is twisted with the fingers and can not be backwards in the cluster area 12.
In the side of suction channel 14 back to suction slot 16, conveyer belt 13 is tightened up by a tension part 23, and this tension part can become the shape of a fixed bar or a deflector roll.Here, tension part 23 is arranged to make conveyer belt 13 to be attached on the output bottom roll 8 with lighter thrust.Because conveyer belt 13 and output bottom roll 8 reciprocally rotate at contact point, so, removed any fibre down that may adhere to from conveyer belt 13.
As shown in Figure 2, the origin zone 24 of suction slot 16 comprises that is widened a part, and its effect is to make suction slot 16 under any circumstance can both hold the fiber skein 2 that laterally moves back and forth easily.This reciprocating motion is particularly useful for guaranteeing that output pressure roller 9 has long service life.
By the Fig. 3 shown in the amplification, the core component of device 1 will be described in detail belows, i.e. Tou Qi conveyer belt 13.
In Fig. 3, conveyer belt 13 is shown ventilative mesozone 25 enlargedly, mesozone 25 is made by the fabric that the thermoplastic silk constitutes.The both sides of mesozone 25 are air-locked marginal zones 26,27, and their edge is represented with symbol 28 and 29.
During fabrication, ground fabric constituted shown in whole piece conveyer belt 13 was at first anticipated as shown by a kind of its mesozone 25.But it is airtight the marginal zone 26,27 of fabric to be become by heating afterwards, thereby, the simultaneously closed mesh of fabric.So, formed the marginal zone 26,27 of smoother, they have guaranteed that generally this conveyer belt 13 has above-mentioned advantageous feature.
If conveyer belt 13 cylinder weavings are become tubular, it does not stitch under finished product state fully.
Can realize heating by variety of way.According to Fig. 3, make these marginal zones 26,27 become airtight by welding by quite wide electrode and especially a ultrasonic electrode.Conveyer belt 13 as the wide B of 25mm has ventilative mesozone 25 and two the air-locked marginal zones 26 and 27 that wide R1 of 7.5mm or R2 are arranged respectively that have as the wide M of 10mm.
In embodiment according to Fig. 4, an identical ventilative mesozone 25 with width M is arranged again, mesozone 25 is made by the thermoplastic monofilament.Can also see from Fig. 4 that braided structure prolongs and the whole width B of conveyer belt 13 at downside.But different with the embodiment of Fig. 3, Fig. 4 has stipulated, scribbles hot melt adhesive 32 or 33 on these marginal zones 30 and 31 each comfortable end face.Therefore, this time, the open-work on the fabric bottom surface is not closed, although gluing also makes marginal zone 32 and 33 become airtight from end face.
