Description
The application is that original bill application number is 200610107494.9, denomination of invention for " for the conveyer belt of transporting fibre band ", the applying date be the dividing an application of application for a patent for invention on July 26th, 2006.
Technical field
The present invention relates to a kind ofly for transporting the conveyer belt of the fiber strip of wanting pneumatic compacting, its breathable fabric of at least being made by a kind of synthetic thread in the position of a guiding fiber strip forms, and wherein fabric is added with the material that has reduced static.
Background technology
If directly and then the outlet roller of a drafter, to the fiber strip spinning twisting that makes one to stretch, just produces a so-called spinning triangle at the right clamping lines place of outlet roller so on a spinning machine.This is that the fiber strip of the stretching of definite width leaves drafter and twisted becomes a relatively yarn for minor diameter owing to having.Spinning triangle comprises edge fiber, they do not inweave in the yarn of twisting in accordance with regulations and the intensity of the yarn being therefore spun into for extruding seldom or there is no what help.Therefore people start to arrange a so-called compacting zone recently after the drawing zone of drafter, and it is demarcated with a clamped position at outlet side.Only have and just make after this yarn spinning twisting.In compacting zone, make yarn boundling or compacting, make like this fiber strip when leaving last clamped position, become so narrow, to such an extent as to the spinning triangle of worrying has no longer adversely played a decisive role.The yarn that is spun into of extruding becomes more evenly, more firmly and fine hair still less.
Known have many different devices for compacting fiber strand.Many these a kind of ventilative conveyer belt work for device, this conveyer belt on a bothrium slidably transport point want the fiber strip of compacting.For example in DE 10 2,004 005 953 A1, disclose a kind of conveyer belt for such device.Many methods that how can stop transportation to take up static have been described in the document.Owing to having stoped a static just to make fine hair substantially not stick on conveyer belt, thereby make fabric keep gas permeability.
It should be noted, concept in the term of this patent application " pneumatic compacting " also should comprise these devices herein, in these devices, also has other mechanism except suction airstream, and the transport assembly of for example aiming at tilting bothrium can acting in conjunction.
The environmental condition of using such conveyer belt is usually very disadvantageous.Room temperature is high, and air humidity is also high simultaneously.In addition conveyer belt is subject to the effect of chemical substance and dust, and they can stick on the fibrous material of processing and thereby arrive on conveyer belt.This environmental condition may cause: the performance that has reduced static is affected adversely greatly.When further using conveyer belt, observe again identical easy susceptibility, it says it is known for the conveyer belt that does not reduce electrostatic material.Can infer, environmental condition has caused the reduction of conductive capability when using such conveyer belt.
Summary of the invention
Task of the present invention is further improve known conveyer belt and make easy susceptibility less within a long as far as possible time period.
This task is by solving as follows: the Ohmic resistance of conveyer belt is less than 10
10ohm.
By conveyer belt, be less than 10
10ohm, is preferably even less than 10
6the Ohmic resistance of ohm has just guaranteed: conductive capability has enough deposits, even so that because environmental condition is also guaranteed enough conductive capabilities when the performance that has reduced static affects adversely within the service life of conveyer belt.
According to the advantage of conveyer belt of the present invention, be that functional reliability is high, within service life, easily susceptibility is little.This advantage can be by making the Ohmic resistance of conveyer belt be less than 10
6ohm is further strengthened.
In design of the present invention, can further improve as follows functional reliability: even if the Ohmic resistance of conveyer belt is also less than 10 after moving 1000 hours
10ohm.By making Ohmic resistance be less than 10
10ohm, is preferably even less than 10
6ohm just guaranteed: conductive capability within remaining service life enough for having stoped to a great extent static.In order to reach desirable conductive capability in operation after 1000 hours, can stipulate, make Ohmic resistance under new state far below operation 1000 hours value afterwards.In this processing mode, make conductive capability for the service life of conveyer belt, have enough large deposit.If Ohmic resistance improves slowly during use, that is harmless.
But also maybe advantageously, add the material that has reduced static to fabric, this material changes hardly its performance under the service condition of conveyer belt.Applied metal line or make synthetic thread when metallization advantageously apply a kind of reaction metal very slowly in fabric.It can be for example gold.Can be to a great extent when selecting like this material that has reduced static at whole operating period chien shih conveyer belt, reach one and be almost constantly less than 10
10the Ohmic resistance of ohm.Within whole service life, can guarantee that transportation is with little easy susceptibility.
For measuring the Ohmic resistance of such conveyer belt, can consult German standard DIN IEC 93(VDE 0303 Teil 30) and DIN IEC 167(VDE 0303 Teil 31), the method for inspection of the material with such Ohmic resistance has been described in these standards.
Accompanying drawing explanation
Other advantage of the present invention and feature are visible following to an embodiment description.Accompanying drawing is depicted as:
Fig. 1: for a stretching of compacting, not yet the device of the fiber strip of twisting, can be used in this device according to conveyer belt of the present invention,
Fig. 2: the view in Fig. 1 arrow II direction, wherein each roller has all removed for the purpose of more clear,
Fig. 3: for measuring the amplification sketch according to the device of the Ohmic resistance of conveyer belt of the present invention.
The specific embodiment
In Fig. 1 and 2, only meaned at spinning machine, especially in ring spinner, be used for compacting stretched, the position of the device 1 of the fiber strip 2 of spinning twisting not yet.Device 1 drafter 3 and then, and drafter 3 has just been expressed outlet roller 4 and one is positioned at above on transporting direction A, has the small band roller pair of a bottom small band 6 and a top small band 7.Outlet roller comprises to 4 the output press roll 9 that a driven output bottom roll 8 and elasticity press to it.Outlet roller has been stipulated an output clamping lines 10 to 4, and it has formed the terminal of the drawing zone of drafter 3.
3 li of drafters, in known manner fiber band or rove 11 are stretched to desirable fineness on transporting direction A always.Be stretching in output clamping lines 10 places and stop, and from this position, be exactly stretched but the fiber strip 2 of twisting not yet.In order to reduce known and to think that and then disadvantageous spinning triangle, fiber strip 2 export clamping lines 10 in the compacting of 12 li of compacting zone.The device 1 that is used for carrying out compacting comprises a ventilative conveyer belt 13, this conveyer belt by 2 transportations of the fiber strip of wanted compacting through compacting zone 12.Device 1 also has a suction channel 14, and it is designed to the hollow type face in negative pressure and can be arranged on many spinning position.At it, on the outline of compacting zone 12, suction channel 14 is for guiding the sliding surface 15 of conveyer belt 13.
15 li of sliding surfaces, have a bothrium 16, it arranges slightly obliquely with respect to the direction of motion of conveyer belt 13, so a side of bothrium 16 is designed to fibre guide limit 17 with respect to the fiber strip 2 of wanted compacting.When compacting, fiber strip 2, along movement on this fibre guide limit 17, so just makes to be positioned at fiber boundling or compacting transverse to the transporting direction of conveyer belt 13 of 2 li of fiber strips, and therefore fiber strip 2 is involved in a little.Suction channel 14 is connected in a negative pressure source of not expressing by one with the spaced apart negative pressure interface 18 of bothrium 16.If suction channel 14 is arranged in a plurality of spinning, position is upper, and each suction channel 14 only needs respectively a negative pressure interface 18 so.
After output clamping lines 20, the yarn 22 of generation is by spinning twisting, and its method is it to be flowed on outbound course B to a unshowned twisting mechanism, for example a ring ingot.For spinning twisting, this output clamping lines 20 plays the effect of twisting locking, and therefore spinning twisting does not have the opposite effect and is stretched over 12 li of compacting zone always.
That side that deviates from bothrium 16 at suction channel 14 makes conveyer belt 13 tensionings by a tension element 23, and this tension element for example can be designed to fixed bar or can be also guide roller.The layout of tension element 23 should guarantee to make conveyer belt 13 to lean against on output bottom roll 8 with little thrust.Because the hair that flies that conveyer belt 13 and output bottom roll 8, at contact position place opposite direction, therefore remove conveyer belt 13 for example to be adhered to.
As seen from Figure 2, the beginning position 24 of bothrium 16 has an enlarging, and its object is, makes under any circumstance all by bothrium 16, to catch reciprocal slightly in a lateral direction fiber strip 2.Reciprocating motion is used for especially guaranteeing that output press roll 9 has longer service life.
If the Ohmic resistance of conveyer belt 13 is less than 10
10ohm, is preferably even less than 10
6ohm, that is favourable.Particularly advantageously: even if the Ohmic resistance of conveyer belt 13 is also less than 10 in running after 1000 hours
10ohm, is preferably even less than 10
6ohm.
As supplementing of above-mentioned German standard, in Fig. 3 Succinct representation a kind of being used for measure according to the device of the Ohmic resistance of conveyer belt 13 of the present invention.Chief component is two and surveys rod 27,28, the conveyer belt 13 that has dotted line to represent above them.First surveys excellent 27 positions remains on 29 li of bearings that is expressed as prism regularly, and the second survey rod 28 is loaded on by direction shown in arrow by pretightning force F, so that tensioning conveyer belt 13 also guarantees the contact that there is regulation between rod 27,28 and conveyer belt 13 surveying.If survey rod 27,28 with shown in mode mutual stacked layout in vertical direction, pretightning force F just can produce by surveying the gravity of excellent sense weight 28 or fixed thereon very simply so.In order to guarantee to survey good electrically contacting between rod 27,28 and conveyer belt 13, maybe advantageously: make to survey coating, the especially silver coating that rod 27,28 is provided with one deck good conductive.
On survey rod 27,28, by means of wire 30, be connected a measurement mechanism 32 with 31.32 li of measurement mechanisms, can carry out by different modes the measurement of driving nurse resistance of conveyer belt 13.Can measure by a kind of direct method, wherein measure the DC voltage that is added in conveyer belt 13 and the current strength (current and voltage method) that flows through conveyer belt 13 simultaneously.But also can use comparison method, wherein for example in a bridge circuit, determine the proportionate relationship of the resistance of conveyer belt 13 and a known resistance.The detail of relevant measuring method can be referring to the above-mentioned German standard of quoting.
For measuring, already turned out to be advantageously: survey rod 27 and 28 diameters that have respectively and be roughly equivalent to 1/3 of conveyer belt 13 diameters.When the diameter of conveyer belt 13 is 36 mm, for example advantageously making the diameter of survey rod 27,28 is 12 mm.For a kind of such conveyer belt 13, must advantageously apply the pretightning force F of about 3N.In addition advantageously, survey rod 27,28 and on its excircle, have one deck silvering.
Measurement mechanism shown in Fig. 3 has especially been considered a kind of abrasion on conveyer belt 13 inner sides producing due to the slip of conveyer belt 13 on sliding surface 15, now to be used to measure be no longer the Ohmic resistance of new conveyer belt 13 to measurement mechanism, and this conveyer belt was used in 1 li, device.
