Term in the field of textile machinery and the scope of the invention " dedusting " should be understood that for the purpose of collecting and/or remove dust and for fear of the harmful measure of gathering that forms dust at the sensitization point of textile machine; Dust is produced in weaving and is formed and be dispersed in the air during perhaps weaving is handled, for example through flying cotton.Like this, term " dust " not only comprises with the dust of fiber with cotton grain or velveteen form, and consists essentially of all formed and got into atmosphere in textile technology particulate.
In loom and knitting machine situation, the constant source of this type dust is particularly for all
The feeding of type yams, braking and monitoring system, and be used for their guiding, deflection and control
Device, for example yarn harness eye or guide post all are inevitable.Because most of yarns
Quality, but at first be cotton thread, cause the formation of a large amount of fine hair, the segment of fluffing is easy to
Be deposited on the other machines element, there their form the coma that increases gradually dimensionally or
Person's egagropilus, and its possibility of result weakens the function of each textile machine.Therefore, know usually
On various types of textile machines, equip dust arrester, before dust deposit, be used to remove,
In possible place, any dust of generation.
The known so far dust arrester in textile machine is mainly operated (for example DE7926685Ul, DE3219467A1.US3422640, EP0531 019Bl) through air blast and/or aspirator.In these some have complicated air distributor arrangement so that air blast and/or suction nozzle can be arranged on each textile machine position as much as possible.Dust arrester is integrated in the Yarn feed device in this literary composition (EP1053196Bl for example; WO01/18295) also be known; And dust arrester mainly is to handle textile yarn with the zone maintenance that forms coil dustless (for example WO95/09259, EP 0,816 546 A2) for those that make circular knitting machine by knitting implement.
Therefore, such dust arrester technical sophistication and be accompanied by the higher-energy consumptive use
In producing compressed air and/or suction air.In addition, air blast and/or suction nozzle usually cause the difficult application point that arrives, and this also makes R and M become difficult.
In addition, it is known being used to remove the device that is deposited on the online dust of mobile material, for example
On paper, weaving or plastic wire, through fed the suction station at net before, use electrode to be material
Material net electrostatic charging and/or discharge (for example W091/12095, DE4120973A1, DE10018 010A1, DE19525453Al, DE19711342 A1).This has considered such physical phenomenon, the non-conducting material net be dispersed in the dust in air particulate usually all be by contact and/or frictional electricity by charged electrostatically, in the situation of opposite polarity, produce strong especially adhesion.Handle web material with charging and/or sparking electrode and therefore should the static neutralization adhere to dust above that, and therefore weaken electrostatic adhesive force.Yet this device only allow to be handled those and has been deposited on the dust on the web material, for example on weaving of accomplishing or knitwear.In textile machine particularly by dust with fly the cotton problem that produces device solves thus.
Summary of the invention
From then on prior art is set out; The technical problem that forms the present invention basis provides a kind of knitting machine that has dust arrester; It does not need complicated air guiding device; Therefore the dust arrester than known is simpler in design, and handles by having the undersized relatively air blast that is used for air blast and/or suction.
In order to address this problem, the present invention provides a kind of dust arrester, but it comprises at least one charged electrostatically gathering element and a device that is used to remove the dust of being collected by the dirt collection element.
The present invention is based on such design, attract charged dust particle, remove the dust that gathers from gathering element then through the charged electrostatically gathering element.In a special preferred embodiment of the present invention, use a moving belt for this purpose.This band is recharged at a charging station, therefore during it is transporting along projected route, can from ambient atmosphere, collect dust, perhaps because this dust of charge attraction gravitational attraction.In addition, this band is configured in the charging station rear on moving direction a discharge station is neutralized electric charge, for example in order to unclamp the dust of collecting on it and can be easy to remove dust through aspirator.Therefore can replace many necessary suction and/or air-blast nozzles in the past according to dirt collection element of the present invention, so, in principle, the dust that removes collection is only needed a central aspirator.
Further favorable characteristics of the present invention can be found out by dependent claims.

Such circular knitting machine has been that conventionally known to one of skill in the art (therefore DE7926865Ul for example DE3628851A1), and does not need more detailed explanation usually.
According to the present invention, described circular knitting machine is equipped with a dust arrester.In said embodiment, up to the present be considered to a kind of of the best, it comprises a dirt collection element 16 that is the continuous belts form of being processed by highly-resistant material, and said band is illustrated by chain-dotted line in Fig. 2.This dirt collection element 16 is in abutting connection with the outer surface region that leans against many guide rolls 17, and this guide rolls can be rotatably set on the mounting 18 and preferably can be around the axle rotation that is parallel to rotating shaft 3.This guide rolls 17, the same with Yarn feed device 9, distribute and suitable being arranged in the plane round rotating shaft 3, wherein mounting 18 is fixed on the support 8a of same chiasma type with supporting ring 8.In addition, a 17a in the guide rolls preferably is constructed to driven roller.This driven roller 17a is fixed; For example; On the driving shaft 19 of a motor 20 or analog; Consequently gathering element 16 can be configured to around said rotation 3 a selected direction of rotation rotation or carry out translatory movement, and for example, (arrow v) a counter clockwise direction among Fig. 2.
Shown in Fig. 2, stand 21 is determined and is used for to banded gathering element 16 electrostatic chargings as especially, and said station comprises at least one charging electrode 22 (map 3 equally), relies on this charging electrode gathering element 16 can fill with positive electricity or negative electricity, decide as circumstances require.In addition; Be positioned at a not far point of 21 the place aheads, station towards the direction of motion; A device that is used to remove dust is provided, and it comprises station 24 (Fig. 2 and 4) in this embodiment, and it is set the discharge that is used for gathering element 16 and has at least one discharge electrode 23; And a dust withdrawing device 25 (Fig. 2 and 5), said withdrawing device is suitable to be set between two electrodes 22 and 23 on gathering element 16 directions of motion.As shown in Figure 2; Withdrawing device 25 has two extractor displacers or suction hood 26; 27, for example, the latter be set at the relative wide side of collecting belt 16 and in their open side edges towards being with 16; Yet the rear side of suction hood 26,27 is connected to a suction fan (not shown) through pipe 28, and it is as shown in Figure 5 along direction of arrow work.
Collecting belt 16 is preferably processed by highly-resistant material, for example polyvinyl chloride (PVC) or rubber.High impedance behavior reaches such purpose, promptly keeps being applied to by charging electrode 22 electric charge on gathering element 16 specific parts during the transporting of arrow V direction as far as possible longways at it, arrives charging electrode 23 up to it together with the electric charge above it.This means that this gathering element 16 needn't recharge the loss of charge that causes with compensation self-discharge or analogue between two electrodes 22,23.
The basic following work of described circular knitter:
In the operation of circular knitting machine; Electrode 22,23 is connected with station 24, and gathering element 16 is impelled along arrow V direction (Fig. 2) through CD-ROM drive motor 20 and on a motion path, rotates; This motion path is through guiding and/or driven roller 17, and the position of 17a is by preset.Simultaneously; Gathering element 16 is filled positive electricity or negative electricity through charging electrode 22; Therefore one of gathering element 16 then the part that is recharged that is provided with continuously move towards the direction of sparking electrode 23; And in that way, utilize the opposite polarity in the zone that is located at gathering element 16 to attract all dust particles through electric power.The dust particle that is attracted then keeps adhering on the gathering element 16, arrives discharge station 24 up to corresponding region.Gathering element 16 is discharged or charge neutrality through discharge electrode 23 in this station, so that the dust particle that electrical affinity is removed and quilt is carried just relatively loosely is attached on the gathering element 16 now.Each region is fed the withdrawing device 25 that is placed in 24 back, discharge station along carriage direction then; Pass suction hood 26 there; 27 the zone of action and therefore gets into the dust particle of stepping down on it before beginning once more with described circulation at discharge station 21 once more at them and removes from two broad side surfaces.Like this, can be short as much as possible in the direction path that quilt is recorded 22 from sparking electrode 23 to charging electrode of arrow v, therefore have only a bit of of gathering element 16 circumference not to be used to collection all the time and to transport dust.If a kind of material that has not enough high impedances is used to gathering element 16, certainly, several discharge stations 21 also can be set up along its motion path.
In order to give banded gathering element 16 chargings, a guide rolls 17b (Fig. 2) who directly is provided with facing to charging electrode 22 can be provided, said guide rolls is for example made by a kind of material resemble the lucite, so that it is as an excitation roller.This can be understood that to mean that this guide rolls 17b and gathering element 16 have opposite electric charge as the result who electrically contacts in this example, i.e. close contact (or friction) and separation then owing to them is recharged.Like this, charging electrode 22 can be set to point electrode, and its effect through opposite polarity is directed roller 17b charging, and gives the banded gathering element that moves through it 16 chargings through corresponding point or corona discharge again.Gathering element 16 then can, in the way of sparking electrode 23, as stated, all dust particles that attract electrically to be filled with opposite charges are to above it at it.As selection, yet guide rolls 17b also can be made and be used as the counterelectrode of charging electrode by a kind of conductive material.
Described dust arrester has lot of advantages, that is, only need a kind of common dust to attract band to be used for many feeding units 9, and removing of its dust can promptly, be on the position of withdrawing device 25 at this a single center point completion.And; Very clearly be positioned in the situation in many planes for Yarn feed device 9 and 10 (Fig. 1); A dust arrester that separates with the mode of similar Fig. 1 to 5, has corresponding charge or discharge electrode 22; 23 and withdrawing devices 25, and can be assigned to wherein each independent plane.
If described dust arrester is used in the plain stitch machine in the circular knitting machine; Then it is possible; For example, make banded gathering element 16 one basic along rotating on the linearly extended elongate path, this track has two parallel strands rather than circular.If so; It may carry out the discharge of gathering element 16 in the charging of a reentry point execution gathering element 16 and at another reentry point of plain stitch machine support in addition; And gathering element is placed in a horizontal plane, thinks that on this plane having maximum dusts produces.
Substitute the band of motion, also other gathering element can be set,, deposit charged dust particle above that or the dust particle that is polarized at electric field particularly with the form of chargeable catch tray or analog.And can this dish be set at the independent application point of textile machine, particularly at independent Yarn feed device place.Like this, through in the electric power usually with catch tray so that allow dust particle to fall because of gravity, dust can be removed, or removes them through other means.
In addition, the electrode that is assigned to these can be provided for to the gathering element charge or discharge with device, as the electrode and device (document of explanation above the reference) of peeling off dust from textile web or analog.In this case, the high-voltage value that possibly be applied to electrode should be selected according to each situation, particularly selects according to the generation of dust in each situation.For a little required electric wires refer to label 30 and 31 in Fig. 3 and 4.
The invention is not restricted to described embodiment, it can many modes change.For example, with situation about being removed, it will also possibly provide dust to remove device for the dust of opposed polarity, makes it have the gathering element that has corresponding opposed polarity and/or provides owing to highfield has the dust that can select polarity.In addition, gathering element can be assigned to other unit that is different from said Yarn feed device.In principle, it can add a device that removes device corresponding to one of them above-mentioned dust and dust (flint) to all yarn deflection units, and also can be in the thread-carrier zone.Except withdrawing device 25, also at least one air-blast device can be provided so that quicken or strengthen the separation of dust from the gathering element that is configured.According to the quantity of dust, can two or more work stations and withdrawing device be provided along the direction of transfer of gathering element 16 after charging station in addition, so that promote the removal of being piled up dust thus.In addition, those knitting machine kinds that are different from Fig. 1 or 2 can be equipped dust according to the present invention and removed device.Title " band " should comprise that all are fit to the cross section of said purpose in very clear all here situation, specifically is rectangle, square, or also can be circular cross-section.At last, it must be understood that also to combine different character, and the situation that is different from diagram and explains.
