As shown in Figure 4, the opposite walls 38 relative with the first air flow hand-hole 31 in aspirating air pipe 20 is constituted as along with the mode of extending downwards with near rear side tilts.First wall 35 constitutes vertical substantially with respect to the face that is provided with of automatic bobbin winder 10 as mentioned above, and therefore above-mentioned opposite walls 38 tilts with respect to first wall 35.Therefore, flow into the air of aspirating air pipes 20, guided downwards along the inclination of opposite walls 38 from the first air flow hand-hole 31 that forms at first wall 35.By will guiding along certain orientation, thereby can in aspirating air pipe 20, produce the air flow of cyclic motion from the first air flow hand-hole, 31 leaked-in airs.
In addition, the aspirating air pipe 20 of present embodiment constitutes, and makes the medial surface (inwall) of whole sheet material of the inwall that constitutes aspirating air pipe 20, and is tangent with respect to the inscribed circle 50 of maximum diameter shown in the chain-dotted line among Fig. 4.Therefore, from the first air flow hand-hole, 31 leaked-in airs, can and can smooth and easyly not flow by the inwall of aspirating air pipe 20 obstruction.
Adopt this structure the attraction of gettering container can be supplied to each winder unit 11 via aspirating air pipe 20.When carrying out the joint operation in winder unit 11, the gate of open winder unit 11 sides is to last yarn guiding tube 68 and yarn under working guiding tube 67 effect attractions.The unwanted hard waste that the joint operation produces is attracted by the attraction mouth 71 of the suction nozzle 72 of last yarn guiding tube 68 and yarn under working guiding tube 67, attracted in the aspirating air pipe 20 from the first air flow hand-hole 31 and the second air flow hand-hole 32 respectively.In addition, air flows into constantly from the 3rd air flow hand-hole 33.The air influx of the first air flow hand-hole 31 is bigger in the present embodiment, therefore from the second air flow hand-hole 32 and the 3rd air flow hand-hole 33 leaked-in airs, imports from the air flow that the first air flow hand-hole, 31 leaked-in airs are produced.
In addition, shown in the hollow arrow among Fig. 5, in aspirating air pipe 20, produce the power of drawing to the gettering container side draught by attraction from gettering container.The attraction of this gettering container combines with the air flow that is guided to certain orientation by opposite walls 38, produces in aspirating air pipe 20 and rotates to be spiral helicine eddy flow.Send into hard waste in the pipeline from the first air flow hand-hole 31, the second air flow hand-hole 32 and the 3rd air flow hand-hole 33, be involved in this eddy flow and can be detained in the bottom of aspirating air pipe 20 attracting to carry on the direction.Hard waste by eddy flow is carried to gettering container is recycled in the not shown gettering container.
Then, be that the variation of pentagonal aspirating air pipe 20 describes with reference to Fig. 6 to section configuration.In addition, this variation has the structure identical with above-mentioned embodiment except the section configuration of aspirating air pipe 90 is pentagon, therefore sometimes the part mark same-sign identical with above-mentioned embodiment is omitted explanation.
As shown in Figure 6, the aspirating air pipe 90 of variation is pentagonal form according to its section configuration, forms tubular by sheet material is carried out suitable processing.End at aspirating air pipe 90 is connected with gettering container, produces the attraction stream towards gettering container in aspirating air pipe 90.
The face wall 95 of face side constitutes vertical substantially with respect to the ground plane of automatic bobbin winder 10.On this face wall 95, be formed with the first air flow hand-hole 91, the second air flow hand-hole 92, the 3rd air flow hand-hole 93 respectively with the through hole form in accordance with the order from top to bottom.The diameter of the first air flow hand-hole 91 forms bigger than the second air flow hand-hole 92 and the 3rd air flow hand-hole 93, and is also maximum from these first air flow hand-hole, 91 leaked-in air influxs.
Opposite walls 98 with the first air flow hand-hole 91 is faced mutually tilts in the mode near rear side along with downward extension.By the inclined plane of opposite walls 98 guiding, aspirating air pipe 90 in, form air-flow mobile of circular such certain orientation from the first air flow hand-hole, 91 leaked-in airs.Attraction stream by the mobile of this air-flow and gettering container generation forms eddy flow.In addition, the inwall of whole sheet materials that constitutes the section configuration of aspirating air pipe 90 be constituted as with aspirating air pipe 90 in the inscribed circle 50 of maximum diameter tangent, therefore can the mobile of eddy flow that be produced do not counteracted.
Converge to the eddy flow from the second air flow hand-hole 92 and the 3rd air flow hand-hole 93 leaked-in air streams, also carry by eddy flow from the hard waste of the second air flow hand- hole 92 and 93 inflows of the 3rd air flow hand-hole.Like this, even also can be by produce eddy flow in inside in section configuration is pentagonal aspirating air pipe 90, the hard waste that may be detained in aspirating air pipe 90 be removed effectively.
Then, with reference to Fig. 7 to Figure 10 the analog result of the air flow in four kinds of different aspirating air pipes of section configuration is described.Fig. 7 to Figure 10 overlooks the average discharge distribution (contour distribution) of expression apart from 10mm position, aspirating air pipe bottom surface.Be connected with gettering container at Fig. 7 to the end (downside end among the figure) of aspirating air pipe shown in Figure 10, on the direction of this gettering container, producing attraction.In addition, the air from yarn under working guiding tube 67, last yarn guiding tube 68, yarn storehouse formula feeding mechanism 61 flow in the aspirating air pipe via the air flow hand-hole.
Fig. 7 represents and the relevant analog result of aspirating air pipe 20 (hexagonal cross-section) shown in Fig. 4 etc.Fig. 8 represents and the relevant analog result of aspirating air pipe 90 shown in Figure 6 (pentagon section).In addition, in this simulated experiment, be that rectangle and circular aspirating air pipe are tested also to existing section configuration.Section be rectangular situation as shown in Figure 9, section be circular situation as shown in figure 10.In addition, Fig. 7 represents all that to analog result shown in Figure 10 the average discharge of the inner bottom surface 10mm height (under the situation of section for circle, apart from the height above the 10mm bottom of inner face) apart from aspirating air pipe distributes.It is to represent that according to 1m/s the contour of the part that speed absolute value herein equates distributes that this average discharge distributes.The big part of disorderly degree of this distribution map is represented the big person of air turbulence degree in the pipeline, otherwise the part that the disorderly degree of distribution map is little is then represented the little person of air turbulence degree in the pipeline.
To shown in Figure 10, along with the distance with gettering container increases, the pressure loss increases and the attraction that causes producing reduces as Fig. 7, because this attraction reduces and the inflow air that flows into from the air flow hand-hole, so in four kinds of aspirating air pipes air turbulence takes place all.But the aspirating air pipe of hexagonal cross-section shown in Figure 7, other aspirating air pipes different with section configuration are compared the disorderly less of air-flow.In addition, aspirating air pipe cylindraceous shown in Figure 10, to compare basal area less with the aspirating air pipe of other shape, bigger from the inflow air influence of air flow hand-hole, so the disorder of air-flow is relatively fiercer.
As mentioned above, this aspirating air pipe of above-mentioned embodiment and variation with number of vertex polygon section more than 5, can produce eddy flow in inside efficiently, it compares the loss speed that can reduce to attract direction with existing aspirating air pipe, and the conveying capacity of hard waste is higher.In addition, by above-mentioned experimental result as can be known, wherein the loss speed of the aspirating air pipe of hexagonal cross-section is especially little, and is therefore more satisfactory in analog result with regard to effectively removing hard waste.
As mentioned above, the aspirating air pipe 20 of present embodiment has following structure.That is, to form the section configuration of cutting off by the face vertical with the attraction direction of gettering container (negative pressure source) be polygon to aspirating air pipe 20.In addition, this aspirating air pipe 20 constitutes and produce eddy flow in this aspirating air pipe 20.
Thus, can remove by the hard waste that eddy flow may be detained in aspirating air pipe 20 effectively.Therefore can reduce to remove the attraction of the required negative pressure source of hard waste and cut down the consumption of energy.In addition, because section configuration constitutes polygon, therefore can make up or bending and easily make aspirating air pipe 20 by the sheet material (plate-shaped member) of commute processing.
In the aspirating air pipe 20 of present embodiment, has following structure.That is, aspirating air pipe 20 has first wall 35, and this first wall 35 forms plane and becomes the one side that constitutes above-mentioned section configuration.On first wall 35, be formed with the first air flow hand-hole 31, be used for each winder unit 11 supply attraction to automatic bobbin winder 10.The opposite walls 38 that the first air flow hand-hole 31 is faced forms with respect to first wall 35.
Thus, from the first air flow hand-hole, 31 leaked-in airs, the opposite walls 38 that is tilted shape guides to certain direction, therefore can produce eddy flow efficiently in aspirating air pipe 20.Therefore, can produce eddy flow by forming the first air flow hand-hole, 31 such simple structures.In addition, first wall 35 that is formed with the first air flow hand-hole 31 forms plane, therefore can be reduced at being used for of constituting in the automatic bobbin winder 10 structure to the connecting portion of the attraction path of winder unit 11 supply attractions and the first air flow hand-hole 31.In addition, in present embodiment and variation, the diameter of the first air flow hand-hole 31 forms and be maximum in the diameter of air flow hand-hole, and the influx of air is also bigger.Therefore, when above-mentioned gate was open, the air flow that imports from the first air flow hand-hole 31 played dominating role, therefore can produce eddy flow efficiently.
In the aspirating air pipe 20 of present embodiment, above-mentioned section configuration constitutes hexagon (polygon of number of vertex more than 5).
Thus, can make the section configuration of aspirating air pipe 20 near circular by the quantity that increases the summit.Therefore, in aspirating air pipe 20, become the state that is easy to generate eddy flow, can effectively the hard waste in the aspirating air pipe 20 be removed.
In the aspirating air pipe 20 of present embodiment, the inscribed circle 50 of the maximum diameter of above-mentioned section configuration inscribe, tangent with the whole limit that constitutes this section configuration.
Thus, can not hinder flowing of eddy flow, therefore can improve the ability of removing hard waste because of the shape of aspirating air pipe 20.
In addition, the automatic bobbin winder of present embodiment (fibre machinery) 10 the gettering container that possesses aspirating air pipe 20 and be connected as negative pressure source with aspirating air pipe 20.
Thus, can reduce the capacity of gettering container, and prevent that effectively hard waste is detained in aspirating air pipe 20.
More than preferred implementation of the present invention is illustrated, but said structure can carry out following change.
The structure of the air flow hand-hole that forms on the aspirating air pipe of above-mentioned embodiment can suitably change.For example, be in hexagonal aspirating air pipe in section configuration, on first wall 35 of upside, except the first air flow hand-hole 31, also can form the second air flow hand-hole and the 3rd air flow hand-hole.Like this, the configuration quantity, allocation position etc. that are used for to the air flow hand-hole of each winder unit 11 supply attractions can change as required.
In addition, in the above-described embodiment, the whole sheet material that constitutes the inwall of aspirating air pipe 20 constitutes with the inscribed circle 50 of maximum diameter tangent.Change to but aspirating air pipe also can replace this structure have not tangent with the inscribed circle of maximum diameter.
In addition, constitute in the above-described embodiment, guided by opposite walls 38 and produce eddy flow, but also can the structure that be used to produce eddy flow suitably be changed from the first air flow hand-hole, 31 leaked-in airs.For example, can be formed for producing the groove of eddy flow or guide plate etc. at the medial surface of aspirating air pipe.In addition, be not limited to above-mentioned embodiment produces eddy flow like this in aspirating air pipe structure.Be directed to certain orientation as long as constitute the opposite walls that is tilted from the air of air flow hand-hole inflow aspirating air pipe, the structure of aspirating air pipe puts and can suitably change before this.Adopt this structure, also can be effectively near the hard waste that is detained may the air flow hand-hole in aspirating air pipe be removed.
In addition, though in the above-described embodiment, the section configuration of aspirating air pipe is hexagon or pentagon, is not limited to this structure.For example can suitably change, the section configuration that makes aspirating air pipe is octagon or square etc.
