Description
Technical field
The present invention relates to a kind of duct element, this duct element constitutes the part of a kind of path assembly, and this path assembly is for using in the frame that is equipped with a pneumatic clearer such as a kind of high-count fine spining machine or analog.
Background technology
Generally, frame (being also referred to as fine spining machine) is equipped with a pneumatic clearer, is used for positively catching the fine hair of being exported by a drafting unit when broken end, splits to prevent the yarn that this fine hair influences unfriendly except those yarns that suffer broken end (broken yarn) split.In order to understand the present invention better, at first will describe its prior art in detail.Figure 12 is the view that a known pneumatic clearer is shown.Referring to Figure 12, each pneumatic clearer all comprises a path assembly 31 and a groove 33, this path assembly 31 is provided with to such an extent that go up and extend at the longitudinal direction of the frame direction of this plan (that is perpendicular to), and groove 33 is connected on this path assembly 31 by an air intake duct 32.Each path assembly 31 is connected on the suction box (not shown), and this suction box is arranged on the place, an end of frame.On the other hand, this groove 33 is provided with by the bottom roller 34 along a front and comprises some air entries, and these suction inlets form in the position corresponding to the yarn path, is used for each yarn partly is directed to separately roll from a drawing-off.Also know a kind of single injector formula pneumatic clearer, wherein each suction nozzle is replaced this groove corresponding to each yarn path respectively.
Generally, for the ease of the transportation and the assembling of a frame, the Rack Body of this frame is made many rack units that separate, each rack unit all has a predetermined length.Then, these rack units are transported to the spinning workshop in guest room, so that be assembled into a frame by these rack units are grouped together.For this reason, will need seven or eight duct elements to build a path assembly, this path component placement is at a side place of a frame of a frame, and this frame is all laid 200 yarns in each side and splited.However, still be high for transporting the required expense of these duct elements, because their volume is very big.In these cases, Japanese Unexamined Patent Publication No NO.9-5 3766 (JP-A-9-53766) proposes a kind of body structure that is used for a kind of duct element of frame, it has identical shaped plane by many and divides member to constitute, these identical shaped planes divide member to form by a kind of slab material being cut into appropriate size and shape, so that these minutes members can be piled up mutually to reduce cost of transportation.
As well-known in this technology, the frame of a frame is very long.Therefore, when the form manufacturing that all has certain-length (about 2 meters) with many each part of duct element be used for this frame the path assembly so that its when transportation a large amount of duct elements must be connected with each other.When being inserted in therebetween connecting elements by use when the interconnective method of each duct element is fit to, except must the preparation connecting elements, also require the troublesome work that each duct element and connecting elements are assembled together.Therefore, the cost of installation duct element increases widely.
On the other hand, if each is all made and has uniform wall thickness with each duct element, then have a kind of pyramidal structure by each duct element is formed, and with the smaller diameter portion of a duct element be assembled to an adjacent duct element than the work that makes sure each duct element of ease of assembly of the interconnective method of each duct element in the major diameter part.Yet, (see Figure 12 and 13) as previously mentioned, because each duct element of this path assembly all is equipped with the spill mating part 37b that extends in a longitudinal direction, so its wall thickness increases in this spill mating part 37b zone.Therefore, the smaller diameter portion of a duct element is assembled to partly causing than major diameter of adjacent duct element has a very big masterpiece to be used on this spill mating part in the intermeshing zone of each duct element, and it also causes torsion in each duct element.Even the torsion in each pass element has a very little magnitude, but in the path assembly that is made of a large amount of duct elements, it is very big that torsion just becomes.As a result, this part that utilize that air intake duct 32 is connected to groove 33 on the path assembly 31 can depart from a predetermined desirable position.
And, making the interconnective method of each duct element if use than in the major diameter part by what the smaller diameter portion with a duct element was assembled to an adjacent duct element, the characteristic when then suitably locating the path assembly is in a longitudinal direction met difficulty.More precisely, when a large amount of duct elements interconnect when departing from the longitudinal direction increased by above-mentioned assembly manipulation, the position that utilizes air intake duct 32 to be connected to the groove 33 on the path assembly 31 will move apart this predetermined desirable position.

The specific embodiment
Describe each preferred embodiment of the present invention in detail now with reference to accompanying drawing.In the following description, same label is represented same or corresponding parts.In addition in the following description, should also be understood that some terms are as " left side ", " right side ", " top ", " end ", " preceding ", " back "." case shape ", " diameter " and similar terms all provide word easily, rather than constitute determinate term.
Now, referring to Fig. 1-4, will describe one first embodiment of the present invention.As illustrated in fig. 1 and 2, each duct element 1 is made of a pair of minute member 2 and 3, and it is one is the shape of the sleeve pipe or the hollow case of pentagon section basically.Each all constitutes by for example crooked metallic plate with about 1mm thickness in the branch member 2 and 3, wherein first and second fens members 2 and 3 form and have this shape, make this duct element 1 quilt along a plane in two, extend to intersect orthogonally with its two ends on this plane.Duct element 1 has about 2 meters length, and is processed into taper, so that its area of section increases towards second end (left end as shown in Figure 2) gradually from first end (right-hand member as shown in Figure 2).Therefore, according to present embodiment, when the path assembly that is made of many duct elements of assembling was installed in the frame, first end of each above-mentioned duct element all was positioned at the place, downstream of air-flow, and second end all is positioned at the upstream side place of this air-flow.Difference between the diameter dimension of first and second ends of duct element 1 is basically corresponding to first fen member 2 and second fen member 3 the two wall thickness sum.As an example, if duct element locates to have the height of a diameter dimension such as 200mm at first end (right-hand member among Fig. 2), then diameter dimension or the height of locating at second end (left end among Fig. 2) will be about 202mm, as shown in Figure 4.
End part (first fen member) 2 comprises a plate part 2a, and this plate part 2a constitutes a diapire of duct element 1.Each vertical side along this plate part 2a forms a bow part 2b.More precisely, each bow partly being curved or fold, is the groove 2c of U-shaped so that form one basically, is used to hold a bottom margin part of this hood-like member 3.
Hood-like member (second fen member) 3 is made up of an antetheca 1a, roof 1c of an air intake duct fixation wall 1b and a rear wall 1d, and it forms continuously by crooked metallic plate.More precisely, antetheca 1a and rear wall 1d extend parallel to each other, and have end portion separately, and they form in one plane, and this plane is arranged essentially parallel to roof 1c and extends.Air intake duct fixation wall 1b is formed has through hole 4, is used for fixing there an air intake duct (not shown).According to the type of used pneumatic clearer, that is groove-shaped or single injector type, many such through holes with suitable dimension 4 can be set.That is to say duct element 1 energy and a groove-shaped pneumatic clearer or the coupling together of a single injector type pneumatic clearer.
Referring to Fig. 1, end part (first fen member) 5 is equipped with breach 5a and 5b at its place, two ends respectively, and the material that they remove recess sweep 2b by part forms.Be used separately as localization part 6 by each end face that forms the bow part 2b that breach 5a and 5b produced.Part base plate 2a remains between the breach 5b at the second end place that is arranged at aforementioned duct element 1, and this part base plate 2a so forms, so that its width reduces gradually towards this second extreme direction.When minute member 2 and 3 was bonded together, as shown in Figure 2, the lower end convex part 3a of the front and back of hood-like member (second element) 3 was protruding from the bow part 2b of end part (first fen member) 2 respectively.
Below, explanation will turn to the assembling of the assembly and a path assembly of above-mentioned duct element 1.When assembling duct element 1, end part (first fen member) 2 and hood-like member (second fen member) 3 are so disposed, so that two lower end convex part 3a of hood-like member 3 are positioned in the opposite of the groove 2c of end part 2, this hood-like member 3 is pressed from top to bottom thereon.As a result, two lower end convex part 3a of this hood-like member 3 are inserted into respectively among the groove 2c, and will divide member 2 and 3 to be fixed together.
On the other hand, to make a path assembly in order interconnecting, the first end part (having reduced diameter parts) of a duct element 1 to be inserted the second end part (than the major diameter part) of another duct element 1 by the duct element 1 that will form like this.In this case, as what in Fig. 3 (a) and 3 (b), can see, antetheca 1a, air intake duct fixation wall 1b, the roof 1c that duct element 1 is partly located at its first end, rear wall 1d and diapire are positioned in the inside of antetheca 1a, air intake duct fixation wall 1b, roof 1c, rear wall 1d and the diapire of another duct element 1 respectively.
Because hood-like member (second fen member) 3 is provided with the sweep of stack on its thickness direction, so the first end of a duct element 1 partly can be assembled in the second end part of another duct element 1 without any tangible difficulty.On the other hand, end part (first fen member) instrument has the bow part that is superimposed upon on its thickness direction.Therefore, if bow part 2b extends across the whole length of second fen member 2, then this bow part 2b is that the second end that the first end of a duct element 1 partly inserts another duct element 1 partly is provided with an obstacle.Yet as if the duct element of using according to this situation 1, two duct elements 1 that are joined together are equipped with breach 5a and 5b respectively in the place of the part that is connected to each other corresponding to each duct element.Because the bow part 2b at these part places has been cancelled, so work as by the large-diameter portion timesharing that diameter parts inserts another duct element that reduces with a duct element 1, the bow part 2b of end part 2 does not place obstacles.
In addition, when a duct element 1 inserts in another duct element 1, two lower end convex part 3a that are positioned at the hood-like member (second fen member) 3 that first end (downstream) of a duct element 1 locates are pressed in respectively on the localization part 6, this localization part is located to form at second end (upstream side) of the end of another duct element 1 part (first fen member) 2, and two the lower end convex part 3a of hood-like member 3 that are positioned at the second end place of a duct element 1 are pressed in respectively on the localization part 6, and this localization part 6 forms at the first end place of the end of another duct element 1 part 2.Like this, the length of overlap or part can be limited to a predetermined amount on the longitudinal direction of interconnective duct element 1.
The structure of above-mentioned duct element is enjoyed many advantages, now the effect of these advantages will be described below.
(a) when inserting partly many duct element 1 telescopiforms being interconnected of another duct element than major diameter by the diameter parts that reduces with a duct element, thereby utilizing each mating part of engagement (lower end convex part 3a and bow part 3b) and extending in the vertical along two branch members 2 and 3 respectively when assembling a path assembly after having assembled each duct element that taper is arranged, each mating part that superposes in the thickness of this duct element 1 is mutual superposition not.Therefore, because a power is not that torsion-type acts on this duct element 1, thus avoided the torsion in each single duct element, thereby also avoided the torsion in the assembly of path.
(b) when duct element 1 interconnects, owing to be arranged on the effect of the localization part of locating at the two ends of duct element 16, so the length in overlap on the longitudinal direction of duct element 1 or zone can be limited to a predetermined amount, and avoided deviation on the longitudinal direction of interconnective duct element even as big as hindering the desirable location of groove or air current spray nozzle.
(c) can be by only a mating part (lower end convex part 3a) being assembled to the assembling of carrying out duct element 1 in another mating part (bow part 2b) very simply.And, even when the lower end male portion is divided the width of the thickness of 3a less than concave channels 2c, and between lower end convex part 3a and bow part 2b when gapped, when applying a negative pressure from a vacuum source (not shown) and to the assembly of path, antetheca 1a and rear wall 1d pushed inward, lower end convex part 3a is pressed on the bow part 2b, and therefore can guarantees air-tightness.
(d) when many duct elements 1 being connected by the bigger end that inserts another duct element than small end with duct element 1, localization part 6 can automatically form by remove a predetermined length from bow part 2b, thus each mating part when making up on the thickness direction of duct element 1 mutual superposition not.
(e) because duct element 1 is made of first fen member 2 and second fen member 3 as end part, this first fen member 2 forms diapire, and other wall of second fen member 3 formation duct element, so wherein forming the structure of mating part in the middle of antetheca 1a and rear wall 1b compares, the inner wall surface of duct element 1 can be made flatly, and be used for the tack rag that to fly upward and fiber and become very difficult in the middle of remaining on the path assembly.
(f) because their structure that taper is arranged makes interconnecting easily of each duct element.
(g) because being formed, an end of duct element 1 has a tapering that reduces gradually towards the downstream direction of this path assembly, so when each duct element being interconnected with formation path assembly, can carry fine hair or analog reposefully, and can not be booked in the office, junction surface in the assembly of path or capture.
The invention is not restricted to the foregoing description, but also can as described belowly implement.
One second embodiment of the present invention is illustrated with reference to Fig. 5.According to this second embodiment, below not inserting second fen member under the situation of convex part 3a, with having is that integrally formed each bow part 2b of first fen member (end part) of U-shaped cross-section can so form basically, so that the width gap at the top section place of this bow part 2b is less than the thickness of lower end convex part 3a, and then lower end convex part 2a is press fit among the bow part 2b.In this case because each lower end convex partly inserts among each concave portions 2b, so can with first minute member (end part) 2 and second minutes member (hood-like member) 3 be bonded together really with a kind of air tight manner.
As shown in Figure 6, replace this structure, wherein the structure of each mating part is such, is about to each convex of lower end and partly inserts among the groove 2c, when convex surface inwards is the surface face to face, at place, the both sides slidingtype formation counterpart 2d of first fen member 2.On the other hand, partly locate to form counterpart 3b, so that can be respectively and the mating part 2d engagement of first fen member at each rear surface of second fen member 3.Also according to the structure of present embodiment, in two parts that each counterpart 2d is removed in the end portion office of first fen member 2, the zone of these parts their stacks when connecting each duct element 1.In this case, two mating part 2d and 3b demonstrate elasticity, and first minute member (end part) 2 and second minutes member (hood-like member) 3 can by with this second minute member (hood-like member) be pressed onto assembling simply on first fen member (end part) 2 from above.Among counterpart 2d and the 3b each can also form towards outer convex surface, and they have identical with structure shown in Fig. 6 basically effect.
Each mating part not necessarily is limited to respect to a shape that the plane is symmetrical, and a center extension of duct element 1 is passed on this plane basically, and intersects orthogonally basically with the two ends of duct element 1.That is to say, extend at center passing duct element basically with respect to one, and the place, both sides, opposite on a plane of intersecting orthogonally basically with the duct element two ends, dissimilar mating parts can be disposed.Fig. 7 illustrates the structure according to a kind of duct element of the fourth embodiment of the present invention.As what can see in the figure, first minute member (end part) 2 be equipped with a bow part 2b at a side place corresponding to antetheca 1a, at the opposite side place corresponding to rear wall 1d, form a kind of counterpart 2d simultaneously, this rear wall 1d representative is towards the convex arc surface of lining.On the other hand, form a lower end convex part 3a and sentence a kind of complementary curved arch shape at second fen member (hood-like member) antetheca 1a place of 3 and form a counterpart 3b at an one lower part, so as can with first minute member (end part) mating part 2d mesh.Also according to the structure of this embodiment, a part of removing each bow part 2b and counterpart 2d, these parts in two end portion offices of first fen member 2 respectively when connecting duct element 1, the area of their stacks.Duct element structure according to present embodiment obtains the advantageous effects identical with first embodiment.
Embodiment 5
Each mating part not necessarily must be arranged on the place, both sides of diapire.They can be arranged on the top side and the place, bottom side of duct element 1.For example, as what can see, comprise first fen member 10 and second fen member 11 according to the duct element of this embodiment in Fig. 8, they comprise antetheca 1a, air intake duct fixation wall 1b, roof 1c and diapire 1e.Top side and place, bottom side at first fen member 10 form each sweep 10b, and this sweep 10b has groove, is used to hold the counterpart 11a of second fen member 11.Also according to the structure of this embodiment, remove the part of each the sweep 10b that forms at first fen member 10 place in two end portion offices of first fen member 10, the area of these parts their stacks when connecting each duct element 1.Structure according to the duct element of present embodiment obtains the advantageous effects identical with first embodiment.
