Description
Technical field
The present invention relates to the reinforced embedded member that in fine spining machine, is used for the suction channel of fiber accumulation device a kind of.
Background technology
In a kind of fiber accumulation device, for a kind of fiber strip that leaves drafter of pneumatic compacting, it is characterized in that: fiber strip is being transported placing in the compacting zone on the ventilative transport element with the fiber that is parallel to each other basically under the still untwisted state, and in compacting zone, produce a kind of air-flow that runs through by transport element, this air-flow has been determined the degree of compacting according to its width and/or direction, and fiber is positioned transverse to transporting direction, and therefore make fiber strip boundling or compacting.For a kind of such fibre sliver, when twisting, just no longer occur the spinning triangle basically, so the yarn that is produced becomes evenly, resistance to wears and fine hair is few.
The reinforced embedded member that starts described kind is known to prior art by DE 100 00 615 A1.Reinforced embedded member on such position-in this position the above conveyer belt that on suction channel, slides compacted by a pinch roll-protection suction channel to overcome wearing and tearing.The outline towards conveyer belt of reinforced embedded member is designed to sliding surface, and it is smooth as far as possible, and makes the frictional resistance of the conveyer belt that slides in the above less.If reinforced embedded member has worn and torn, it just can be replaced, and can replace with a new reinforced embedded member.Int suction channel can continue to use after changing reinforced embedded member no problemly.
Known reinforced embedded member has following shortcoming: its state of wear is difficult to identification and recognizes for the operating staff.Regulation does not have great wearing and tearing to permit on the sliding surface of reinforced embedded member, and does not influence the operation of fiber accumulation device.When the reinforced embedded member wearing and tearing are very big, also can damage suction channel in addition, and equally also must change.Regulation need not changed the moment of reinforced embedded member and the machine operation person's decision of just leaving, and this operator often lacks experience for the estimation in the correct moment.
Summary of the invention
Task of the present invention is to propose a kind of reinforced embedded member of avoiding described shortcoming.
This task solves by the following: reinforced embedded member has a kind of wear indicator.
The advantage of the wear indicator on reinforced embedded member is: the state of wear that indicates reinforced embedded member.Wear indicator has at least two kinds of indicating status for this reason.First kind of indicating status represented: reinforced embedded member is normal.Second kind of indicating status represented: reinforced embedded member has worn and torn and must change.Selectively, before must changing forcibly, can also refer to illustrate a kind of warning, this warning expression will be changed.Therefore machine operation person can know when must change this reinforced embedded member at a glance.
Wear indicator can design like this, makes to be provided with the position that at least one is made by a kind of signal material under this reinforced embedded member sliding surface of being made by first kind of material.Signal material is hidden under the surface and by the sliding surface material and covers under new state.By the wearing and tearing of the reinforced embedded member sliding surface of appearance when moving, the material of sliding surface is denuded step by step by the conveyer belt that slides in the above.If the material of sliding surface has been denuded fully, signal material just reaches the surface and can see so.The visible signal material that becomes indicates: reinforced embedded member has worn and torn and must change.Advantageously, if signal material has the color different with the sliding surface material.For signal material, more advantageously select a kind of color of easy identification, it can be well from the optics separates with the chromatic zones of slidingsurface.
Wear indicator also can alternatively be realized by at least one cavity that is positioned under the sliding surface.If the abrasion of materials of sliding surface has been fallen, that cavity just occurs and indicates: reinforced embedded member must be changed.
Can stipulate, this signal material by a kind of materials similar of and sliding surface or identical materials make, and just by its color and the differentiation of sliding surface material.The failure-free operation that it is hereby ensured fiber accumulation device is until changing reinforced embedded member.Advantageously, if can recognize the essential reinforced embedded member of changing by the described conveyer belt that on reinforced embedded member, moves.In a kind of favourable design, this can reach by the following: signal material is released to color particle the conveyer belt that slides in the above, can on conveyer belt, identify these color particles then, and indicate and to change the reinforced embedded member that is positioned under this conveyer belt.
Description of drawings
Other advantage of the present invention and feature are seen following to explanation that some embodiment did.Accompanying drawing is depicted as:
Fig. 1: the side view in partial cross-section of representing a fiber accumulation device;
Fig. 2: the view of compacting zone on the arrow II of Fig. 1 direction;
Fig. 3: according to the vast scale zoomed-in view of a reinforced embedded member shown in Figure 1 of the present invention.
The specific embodiment
By the fiber accumulation device that is used for compacting fiber strand 21 shown in Fig. 1 and 2 is a kind of part of fine spining machine, preferably the part of ring spinner.Each spinning spindle position of this fine spining machine has one is the drafter 3 that express the part, about this mechanism only expressed an outlet roller to the belt lace of 4 and one front to 5,6.
Described outlet roller is designed to lower roll 7 continuous and driven lower roller on the machine longitudinal direction to comprising one, and this lower roll of each spinning spindle position all is furnished with a pressure roller 8.Lower roll 7 and pressure roller 8 form an output clamping lines 9 mutually, and it finishes the drawing zone of drafter 3.
Along transporting direction A, with a fiber strip or alternatively a coarse yarn 10 flow to drafter 3, and be stretched to desirable fineness in the known manner for 3 li at drafter.
Then the outlet roller of drafter 3 is compacting zone 11 to 4, in this compacting zone, will stretch but still untwisted fiber strip 2 pneumatic ground boundling or compactings.Here the fiber accumulation device 1 that is provided with comprises a ventilative conveyer belt 12, and it makes fiber strip 2 transportations by compacting zone 11.Conveyer belt 12 advantageously is designed to the webbing by the thread thin fine mesh of polyamide.
The port of export of compacting zone 11 is limited by a feed clamping lines 13, and this clamping lines is used as resistance twist mechanism simultaneously, so fiber strip 2 keeps not having twisting for 11 li in compacting zone.Then feed clamping lines 13 just produces yarn 14, and it is fed to a unshowned twisting mechanism, for example one encircles ingot on feed direction B, and in this twisting of spinning.
Fiber accumulation device 1 also comprises a suction channel 15, and it preferably is made of a kind of hollow material with a kind of tube shape matrix that is under the negative pressure.Suction channel 15 advantageously extends on a plurality of spinning spindle positions, and each machine portion section once is connected in a unshowned negative pressure source by a negative pressure joint 16.
In order on supply clamping lines 13, to realize the essential twisting that stops, being provided with a pinch roll 19, this pinch roll drives conveyer belt 12 and also makes conveyer belt 12 and make fiber strip 2 press to sliding surface 17 with certain thrust simultaneously.Pinch roll 19 itself is for example realized its driving by a delivery roll 20 by the pressure roller 8 of drafter 3.
By compressing of 19 pairs of sliding surfaces 17 of pinch roll, in the scope of feed clamping lines 13, produce certain wearing and tearing, this should utilize a reinforced embedded member 21 to overcome.Because be limited to the scope of feed clamping lines 13 according to these wearing and tearing of experience, it is exactly unnecessary therefore especially the gamut of sliding surface 17 all being protected.Outside feed clamping lines 13 scopes, sliding surface 17 has thin coating just enough where necessary.
On each spinning spindle position, in pinch roll 19 scopes, be provided with a reinforced embedded member 21, it is embedded into 22 li of one bag of connected in stars of 23 li of the tube shape matrixes of suction channel 15 under feed clamping lines 13.Reinforced embedded member 21 should be wear-resisting as far as possible and simultaneously also enough smooth, so that make that conveyer belt 12 resistances that slide are less on suction channel 15.Reinforced embedded member 21 is relative narrower on transporting direction A, and it then more practicably is equivalent to the width of pinch roll 19 or the width of conveyer belt 12 transverse to transporting direction A.
In Fig. 3, the encirclement of reinforced embedded member 21 and suction channel 15 part is illustrated in the view corresponding to Fig. 1 greatly enlargedly.Reinforced embedded member 21 is positioned at 22 li of bag connected in stars, and by the extended sliding surface 17 of suction channel 15 of its sliding surface 24.The described conveyer belt 12 that slides on sliding surface 17 and 24 is not shown in this view.Reinforced embedded member 21 can be fixed on 22 li of the connected in stars of bag of suction channel 15 by unshowned fastener, and more advantageously can change easily.
According to the present invention, this reinforced embedded member 21 has a wear indicator 25, and it indicates: when reinforced embedded member 21 has worn and torn and necessary the replacing.Wear indicator 25 is made up of at least one position 26 under sliding surface 24, and this position is made up of a kind of signal material 27.Under state shown in the reinforced embedded member 21, it is equivalent to new state, and position 26 is covered and can't see by the material of sliding surface 24 fully.Position 26 can be extended on the whole length of reinforced embedded member 21 transverse to transporting direction A.But also can be alternatively, as shown in Figure 2, a plurality of positions 26 distribute on reinforced embedded member 21.
At fiber accumulation device 1 run duration, owing to press to the conveyer belt 15 of reinforced embedded member 21 by pinch roll 19, so on sliding surface 24, produce wearing and tearing.By this conveyer belt 12 that on reinforced embedded member 21, slides the material of sliding surface 24 is little by little denuded.The material of the sliding surface 24 on the position 26 of wear indicator 25 thins down.Certain the time sliding surface 24 material fallen by abrasion fully, and the signal material 27 of wear indicator 25 can be seen.Therefore can recognize at a glance: reinforced embedded member 21 must be changed.Advantageously: if signal material 27 has a kind of color different with the sliding surface material, and the words that identify easily when the color of this signal material 27.Therefore the position 26 of wear indicator 25 also can be by seeing the perforation that is positioned at top conveyer belt 12.
Different according to the material of reinforced embedded member 21 and sliding surface 24, if the material thickness of sliding surface 24 on position 26 less than 1mm, especially less than about 0.3 to 0.8mm, that may be favourable.Therefore can realize that the condition of the geometry aspect of conveyer belt 12 and pinch roll 19 does not have too big change, therefore not influence the fiber strip 2 that on conveyer belt 12, transports.Stoped matrix 23 to cause damage in addition to suction channel 15.
A kind of wear indicator 25 of such pattern has two kinds of indicating status.As long as signal material 27 is also covered by sliding surface 24 materials, that is expression just: reinforced embedded member also is applicable to and works on.In case the fret wear of sliding surface 24 has fallen, the indicating status of wear indicator 25 has taken place to change and point out so: reinforced embedded member 21 must be changed.This is enough for many ranges of application, and especially reinforced embedded member 26 becomes and as seen then do not lose its function suddenly at the position.
In design of the present invention maybe advantageously: wear indicator 25 can present a kind of indicating status, it be used as the warning and point out: reinforced embedded member 21 directly is faced with replacing.Position 26 for example can be furnished with a less position 28 that is shown in broken lines in Fig. 3 for this reason, and this position is arranged on the position 26.This less position 28 or 29 for example can be designed to cylindrical 28 or also can be designed to conical 29. Position 28,29 equally also can be made by a kind of signal material, yet, can have the different color of a kind of and signal material 27. Less position 28,29 at first can be seen and be indicated when the fret wear of sliding surface 24: reinforced embedded member 21 is faced with replacing.21 of reinforced embedded members can also never have problem ground and continue to stay 1 li of fiber accumulation device, until the position 26 that can see wear indicator 25 and indicate: must change.
By the thickness at less position 28,29, be set between the signal of first caution signal and replacing requirement this also remaining working time of reinforced embedded member 21.
Also maybe advantageously position 26 or 28 is designed to taper shape, perhaps on the direction of sliding surface 24, is diminishing gradually.Therefore slowly become the color component of the big signal material of seeing 27 as time passes by this and in fact realize a kind of similar indication performance of wear indicator 25.If position 29 is for example formed by many little cones, they all use its most advanced and sophisticated sliding surface 24 that points to, and at first form the little circle that can see of signal material 27 so on sliding surface 24, and it is big that these circles more and more become along with the increase of wearing and tearing.Therefore can predict the moment that reinforced embedded member 21 faces essential replacing and predicts replacing.
In another kind of design advantageously: come the signal material 27 of selection part 26 like this, it be discarded to colored particle on the conveyer belt 12.Therefore the replacing of necessity of reinforced embedded member 21 just can be seen more significantly.
