As Fig. 1, shown in 3 (a) etc., near each suction tube 45 bottom, be furnished with the bleed leading section of the suction nozzle 48 of knowing system of single type, be suitable for the fiber bundle F that suction is sent from drafting system 11 when broken string.The base portion end of this suction nozzle 48 is connected on the pump orifice 43.
The operation of said structure device will be described below.
When spinning machine moves, fiber bundle F drafted between bottom roller 12 to 14 and anterior roller 19 to 21 process, be guided fiber accumulation device 30 subsequently.Clamping roller 31 rotates with certain speed that is higher than anterior roller 12 and 19 superficial velocities in pairs, and through behind the bite of paired clamping roller 31, fiber bundle F is released at suitable stress condition, and moves downstream in afterturn.
In addition, at clamping roller run duration, the suction behavior of pump orifice 43 arrives suction tube 44 and 45 through tube connector 47 and tube connector 46, and the suction behavior of suction socket 44a in slide-and-guide face 44b and 45b and 45a arrives fiber bundle F through air-permeable apron 33.Fiber bundle F moves to be sucked collected state in the position corresponding to suction socket 44a and 45a as a result.
If as traditional device, suction socket in the structure (slit) only is arranged in the upstream of bite, shown in Fig. 9 (b), through before arriving bite again behind the bite, decontroled by the fiber bundle F of concentrating, gone out the triangle T that the interruption-forming roller surrounds at paired clamping roller 31; So, the fiber bundle F two ends fiber separation through bite just can not be limited to enough degree, and the result produces lint.But, in this embodiment, on the upstream and downstream of paired 31 bites of clamping roller, suction socket 44a and 45a are arranged all, so, even behind the process bite, fiber bundle F can also be to be moved by collected state under swabbing action.In addition, shown in Fig. 9 (a), in fact do not form the triangle that roller surrounds in paired clamping roller 31 outlets at all.As a result, the fiber bundle F two ends fiber separation through bite is restricted, has limited the generation and the waste cotton of lint.Thereby fundamentally improved line mass.
In addition, owing in the downstream of bite suction socket 45a is arranged, concentrated effect also can expand the bite upstream to a certain degree, thereby has limited its separation before fiber bundle F arrives bite.
This embodiment has the following advantages:
(1) owing in each unit of a plurality of spindles, all has turning cylinder 34 that rotates bottom clamping roller 34a and the suction section 32 of on drafted fiber bundle F, implementing swabbing action, and, turning cylinder 34 is that (end plug 39) supported in supported many places, therefore, be convenient to installation, maintenance and replacing air-permeable apron 33.In addition, even driven clamping roller (top clamping roller 31a) does not have excessive bending stress yet and is applied on the turning cylinder 34 by the middle part extruding bottom clamping roller 34a of air-permeable apron 33.
(2) because gear 40 is the torque transfer members that the torque of drive source sent to turning cylinder 34, therefore, do not resemble the situation that the torque transfer member is made of the friction roller, needn't contact the driving source with energetically the torque transfer member being pressed, and strengthened the free degree of arranging, simplify the structure.In addition, compare by the situation that constitutes, simplify the structure around connecting gear with the torque transfer member.
(3) because roller of the anterior end 12 is the drive sources that rotate turning cylinder 34, therefore, needn't on spinning machine machine bottom, newly provide the drive source that drives turning cylinder 34, thereby simplify the structure, reduced production cost.
(4) because aspirator (suction section 32) is furnished with tube connector 46, tube connector 46 is connected on the pump orifice 43 that is arranged on the spinning machine machine bottom and provides controlled underbalance for suction tube 44 and 45, and, suction tube 44 and 45 can be separately connected on the tube connector 46, further is convenient to the replacing of air-permeable apron 33 and to maintenance activity of suction tube 44 and 45 etc.In addition, when causing suction tube 44 and 45 damages to be changed because of friction with air-permeable apron 33, needn't be with the integral replacing suction section; Only need to change the suction tube 44 and 45 that damages, therefore, be convenient to change operation, can reduce cost.
(5) because supported parts (end plug 39) can inject among support portion 15a and the 37a with single movement, therefore, the installation and removal of turning cylinder 34 have further been simplified.In addition, because support portion 15a and 37a have fitting recess 15b and the 37b that is bent upwards extension in front side, machine bottom, can be by support portion 15a and 37a with pack into state fixed bias circuit 34 reliably among fitting recess 15b and the 37b of supported parts (end plug 39), thus turning cylinder 34 and the installation of suction section 32 on the spinning machine bottom further simplified.
(6) because the two ends of turning cylinder 34 all have supported portion, therefore, compare with the situation of the supported portion that in the middle of turning cylinder 34, is provided with, be convenient to the installation of supported portion.In addition, the support portion that is used to support the supported other end (end plug 39) of adjacent rotated axle 34 is shared, thereby can reduce the number of the 37a of support portion portion, reduces the cost of fiber accumulation device 30.
(7) install on the turning cylinder 34 by bearing 38 pars intermedias owing to supported parts (end plug 39), and have as supporting suction tube 44 and 45 end support functions of components, therefore, be easy to determine to drive on the turning cylinder 34 that the relevant position between suction socket 44a and 45a concerns in roller part (bottom clamping roller 34a) and suction tube 44 and 45.
(8) owing to supported parts constitute by blocking suction tube 44 and 45 open-ended end plugs, therefore, the end plug 39 that utilization is used as supported parts has blocked the pipe end effectively, blocks these ends of suction tube 44 and 45 when noting be used in suction tube 44 and 45 productions away from negative pressure source.So, be convenient to the production of suction tube 44 and 45.
(9) because the part of aspirator (suction section 32) is arranged in the torque transport unit, so that the lid of available torque transport unit (gear 40), therefore, cotton dirt etc. are difficult for being accumulated on the torque transport unit.
(10) because suction section 32 all is furnished with suction socket 44a and 45a between the upstream and downstream of paired clamping roller 31 bites, therefore, fibre bundle even through all under swabbing action, moving behind the bite, to such an extent as to can not form the triangle that roller surrounds in the outlet of bottom clamping roller 34a with collected state.The result can limit the generation and the waste cotton of lint, thereby effectively improves line mass.
(11) owing in the downstream of bite suction socket 45a is arranged, concentrated effect can be to expand to the upstream of bite, so fiber bundle F its dispersion before arriving bite is restricted, thereby further improves localization effects to a certain degree.
(12) because the woven material of air-permeable apron 33 usefulness is made, so the making of needn't requiring efforts is formed with the aperture of porous material 33 belt bodies, by selecting can guarantee to have the woven material of suitable degree gas permeability, just production air-permeable apron at low cost 33.
(13) because end plug 39 has the support portion 15a of threading and the fitting recess 15b of 37a and the 39a of department of assembly among the 37b, and, by the stress of distributing to tube connector 46 from tube connector 47 this end plug 39 is fixed on the precalculated position, so, fiber bundle F can be accepted swabbing action from suction socket 44a and 45a with stable state, thereby has stablized line mass.
Structure is not limited to the foregoing description, for example, also can adopt following structure:
Turning cylinder 34 and suction section 32 are not defined as a unit of four ingot structures, can constitute a unit yet by the ingot of 15 of roller stands.In this case, can reduce the partial amt of necessary suction section 32 of spinning machine and turning cylinder 34, and, can reduce the number of the tube connector 47 of connection pump orifice 43 and suction section 32, so, necessary workload can be reduced.In addition, generally arrange roller stand 15 in space corresponding to the spring installation interval place that forms the spinning machine bottom shelf, and connected in many cases pump orifice 43 has and the corresponding length in this space, so, if suction section 32 and turning cylinder 34 also adopt the corresponding length with this length, pack in the time of just being convenient to transport etc.
Also can adopt two ingots to constitute the structure of a unit, always not need same number of ingot to constitute all unit.Also can provide two unit as required at 15 ingots (as six and two ingots) that adopt different numbers of roller stand.In addition, turning cylinder 34 also can with corresponding to the length of arranged number of spindles on roller stand 15.
The position of supported portion is not limited to the end of turning cylinder 34 on the turning cylinder 34, and they also can be arranged in the centre position.But they are arranged in end, the easier interference of avoiding suction tube 44 and 45.
The position number of supported portion is not defined as two on the turning cylinder 34, and three or more supported portions also can be arranged.In this case, the length of turning cylinder 34 is consistent with roller stand 15.Preferably utilize the supported portion of roller stand 15 to be arranged in end, also can be arranged in some intermediate point position to supported portion.
Supported (end plug 39) when being fixed to support portion 15a and 37a, also can adopt screw rod and need not press supported (end plug 39) by tube connector 46 and support portion 15a and 37a and fitting recess 15b and 37b and touch assembling.In addition, also the portion of tightening and one supported (end plug 39) can be set in support portion 15a and 37a, and make the structure department of assembly in another supported can tighten portion, be fixed on the precalculated position.
