Description
Technical field
The present invention relates to a kind of air-conditioning etc. the air conditioning refrigerator heat-transfer pipe and be used in hot-water supply, the copper of feed pipe or the level of alloy copper pipe that building uses and twine coil pipe, this level is twined the package body of coil pipe and is twined pipe Supply Method the coil pipe from level.
Background technology
Copper pipe or alloy copper pipe (following copper pipe comprises the alloy copper pipe) are used for the heat-transfer pipe (there are fluted tube and smooth tubes in inside) and the hot-water supply pipe and the feed pipe for building of the air-conditioning equipment of air-conditioning etc.This copper pipe, in manufacturing process, anneal after for example coil-like winding working procedure reach fixed modifier treatment, with coil pipe (level is twined coil pipe LWC:Level Wound Coil) state keeping and carry.
Figure 10 explanation level is in the past twined the profile of the winding method of coil pipe 110.But for simplicity of illustration, the cross section of pipe 101 is with the circle expression in Figure 10.As Figure 11 and shown in Figure 12, the coil pipe frame 102 that the inner core 102a that can take out and side plate 102b are constituted its axis with level or vertical placement, be installed in whirligig 103 or 104, by this whirligig 103,104, press direction of rotation shown in the arrow (winding) rotating disc pipe support (around axle) 102.Thus, copper pipe 101 is wrapped in coil pipe frame 102.
At this moment, copper pipe 101 at first in the inner core 102a of coil pipe frame 102 peripheral surface, is that top 111 positions winding to the right with illustrated left position at first as shown in figure 10.So-called location is twined and just is meant that a circle of copper pipe 101 and a circle of adjacency contact with each other, and is promptly very close to each other, twine copper pipe 101 closely.Then, copper pipe 101 arrives the right end, finish after the ground floor winding, and be to twine the second layer left specifically from the right end.In the past, become the position above the slit of copper pipe part 112 between copper pipe part that becomes the ground floor terminal and side plate 102b that the second layer twines top, successively, left, it is chimeric that second layer copper pipe partly is wrapped between the adjacent copper pipe of the ground floor part formed recess.Then, the 3rd layer coil pipe is stacked on the second layer coil pipe.Like this, the axial winding of copper pipe 101 towards pipe, form after the ground floor coil pipe, the cylindric coil pipe of the second layer thereon makes copper pipe 101 twine and the winding method of formation is called vertical winding along axial (rightabout) of pipe.Always, the coil pipe writhing number of each layer that vertically twines is identical.By the copper pipe 101 of such winding, can make the little coil pipe of volume 110, can reduce keeping and transportation requisite space, each coil pipe quality of this LWC110 is 100～500kg.The LWC110 of Zhi Zaoing takes out coil pipe frame inner core after its outermost is utilized the copper coin band to prevent to open a book to handle like this, carries out carrying out the modified annealing of wanting in the roller hearth type continuous annealing furnace.
Transportation is during LWC110, the state of coil pipe frame 102 or dismounting side plate 102b and inner core 102a for example is housed takes out the state of coil pipe frame 102 from LWC110, places LWC110 on shelf, makes its coil pipe axle vertical.At this moment, the situation of packing bolster between the situation of only adorning a coil pipe and the coil pipe and stowing a plurality of coil pipes is arranged.Also have, when the outside was covered with corrugated paper, each upright pillars of limit central authorities of four corners of shelf or shelf were fixed on coil pipe the use copper pipe destination of transporting to air-conditioning assembling factory etc. under the state of pillar, in order to avoid when transportation, owing to impact that goods collapses or collision and injured.(opened in fact flat 4 years---No. 91891 communiques, real open flat 4 years-19556, open flat 2 years-124859, real opening flat 7 years in fact---21590).The figure of LWC110 one example when Figure 13 (a) is this transportation of expression.Take out coil pipe frame 102 among the LWC110, use fixedly coil pipe of rope 106,, put the corrugation liner 105 made of paper of bolster between the coil pipe 110 in order to avoid damage the winding state.
Like this, the packing of the LWC that is transported to the destination of opening a book as Figure 11 and shown in Figure 12, is installed in LWC110 on the rotating shaft of whirligig 103,104.Figure 11 is that rotating shaft is a level, is vertical payoff reel and Figure 12 is a rotating shaft.Unpack after this LWC110, shown in Figure 13 (b), to each coil pipe, insert inner core 102a at the LWC110 center, side plate 102b is fixed on inner core 102a with screw, and assembled disc pipe support 102, is wrapped under the state of coil pipe frame 102 LWC110 is installed in whirligig 103,104.So, making the rotation of direction of rotation (expansion coil pipe) shown in the axial rotary arrow of these whirligigs 103,104, the copper pipe part of the terminal 113 when clamping coil pipe shown in Figure 10 twines is pulled out coil pipe, and coil pipe 110 begins from the periphery to launch.
At this moment, in transportation or the keeping, that is, though not the seeing in appearance of coil pipe, when coil pipe was launched, being wrapped near the copper pipe outer surface of coil pipe central authorities had variable color.This variable color is to be caused by forming of oxide-film, is called as the flesh variable color.If such variable color takes place in copper pipe 101, the danger of the reliability when reducing soldering copper pipe 101 is not only arranged, simultaneously also bad in appearance, therefore, can not use and discard.Therefore, because variable color, yield rate reduces, production efficiency descends easily.
In addition, coil pipe 110 need be installed in the operation of whirligig 103,104.At this moment, because the weight of LWC110 is big, in order to guarantee safety and the distortion that prevents coil pipe 110, be necessary abundant idea, thereby productivity ratio reduces.
Also have, use whirligig 103 shown in Figure 11,, make its axle horizontal and when opening a book,, become the state of rolling-in coil pipe 110 if the pulling capacity of copper pipe 101 is big coil pipe 110 horizontal positioned.Because this rolling-in, partly enter into gap between side plate 102b and the copper pipe 101 in abutting connection with the copper pipe of side plate 102b, be not easy to extract, the distortion of this part takes place, often become that yield rate reduces, the reason of productivity ratio decline.Simultaneously, in the whirligig 103 shown in Figure 11, support the state of coil pipe, also have, the rotation of this rotating shaft is driven the necessity of carrying copper pipe by the rotating shaft cantilever beam of level, therefore, complex structure, equipment cost height.
In addition, use whirligig 4 shown in Figure 12,, make its coil pipe axle vertical, when the outside of coil pipe begins to open a book, at this moment,, also have power the rolling-in direction of coil pipe owing to act on the pulling force of copper pipe 101 coil pipe 110.Therefore, coil pipe 110 rubs mutually and stays scuff mark or distortion, becomes yield rate and reduces and the productivity ratio main reasons for decrease.
Also have, as shown in figure 12,, make its axially vertical placement and when opening a book, need to place the turntable 107 of LWC110 LWC110.Therefore, whirligig 103 shown in Figure 11 also has the high difficult point of its equipment cost.
Like this, for the LWC110 that opens a book, just needed very big investment to come introducing equipment in the past.Especially, want to control the pulling force of certain pipe of opening a book, be necessary that in the whirligig 104 that comprises turntable 107 intricately controls the rotary speed of its turntable 107, its equipment cost becomes high.
In order to solve such problem, be called as the existing motion of the method for opening a book of the coil pipe of ETS (Eye Tb the Sky).Figure 14 is expression with the open a book stereogram of coil pipe of ETS method.
This method as shown in figure 14, if the coil pipe frame is housed in the transporting equipment, is then dismantled the inner core and the side plate of the coil pipe frame of coil pipe, if the coil pipe frame is not housed, then by keeping its previous status, LWC110 is contained on the estrade 114.At this moment, place LWC110, make LWC110 axially vertical, and, as shown in figure 10, place coil pipe, the top 111 when making the winding that the coil pipe inner face exists is up.Also have, the top 111 when this coil pipe of pull-up twines is inserted into the cylindric guide pipe 115 of the bending that is located at estrade 114 tops to copper pipe 101, changes its route, is fed to the application target ground of copper pipe 101.Like this, coil pipe 110 does not rotate, and copper pipe 101 is pulled out from coil pipe 110, begins to open a book from coil pipe 110 inside, and copper pipe after coil pipe 110 is pulled out 101 forms spiral helicine ring, but in the time of pulling out by guide pipe 115, little by little eliminates the trend of its winding.Also have, 0.2% yield strength is 60.～70N/mm
2The soft phosphorous deoxidize copper tube of degree, when utilizing the ETS method to open a book, because of copper pipe has been applied plastic working, its 0.2% yield strength is brought up to 90～105N/mm
2Degree.
Like this, when utilizing the ETS method to open a book coil pipe, the dismounting inner core when opening a book coil pipe and the time of side plate in order to save, generally a plurality of LWC are not had coil pipe frame state and be contained in shelf and be transported to application target ground, untie packing, be contained under the state of shelf, begin to open a book successively LWC from the upper strata coil pipe in the field of employment.
Among the ETS,, not only reduced cost of transportation, the efficient that has also improved packing significantly and unpacked because of not wanting side plate and inner core.When coil pipe is opened a book, there is no need to rotate coil pipe, the copper pipe of pulling out from coil pipe inside by spiral-shaped rising, is directed to desired copper pipe processing site.Therefore, special equipment such as unnecessary vertical payoff reel or turntable.Also have, in the application target ground of copper pipe, accept after the LWC, transport to and use the scene, just unpack, just under multilayered state, begin to open a book in order, therefore, can alleviate the problem of above-mentioned productivity ratio significantly from upper strata LWC.
In addition, because of the inside from coil pipe begins to open a book, act on the direction that makes coil pipe open so act on the pulling force of pulling out copper pipe.That is, the effect of the rolling-in coil pipe direction power that does not cause by the pulling force of copper pipe 101, thereby prevented the distortion of the pipe in the vertical payoff reel or the frictionally damage of the pipe in the horizontal payoff reel, improve yield rate significantly.
But, in the ETS method, when opening a book coil pipe also often the pipe of generating period fracture, be out of shape, cheat recessed or scratch, this just becomes the obstacle of raising yield rate.
Summary of the invention
The present invention uses for reference the problems referred to above and carries out, it is a kind of when utilizing ETS to open a book coil pipe that its purpose is to provide, do not fracture, be out of shape, cheat recessed or scratch, collapsing of coil pipe do not taken place twine the pipe Supply Method of coil pipe, horizontal winding disc tube packaging body and level winding coil pipe with the level of variable color.
Relevant level of the present invention is twined coil pipe, formation ground floor coil pipe is twined in the pipe location, then, second layer coil pipe location is wrapped in above the ground floor coil pipe, makes above-mentioned second layer coil pipe be entrenched in whole recesses between the pipe of ground floor coil pipe outside, again, with same method, formation multilayer coil pipe is twined in pipe multilayer location, when the writhing number of odd-level is n, the writhing number of even level is (n-1) or (n+1), the winding direction of odd-level is opposite with the winding direction of even level.
Perhaps, relevant level of the present invention is twined coil pipe, formation ground floor coil pipe is twined in the pipe location, then, second layer coil pipe location is wrapped in above the ground floor coil pipe, make the top of above-mentioned second layer coil pipe be entrenched in last end of ground floor coil pipe and the recess between the pipe of circle before it, the back is with same method again, the multilayer coil pipe is twined in the location, recess whole between the coil pipe outermost tube of one deck before the coil pipe of a layer is entrenched in, the writhing number of odd-level equates that with the writhing number of even level the winding direction of odd-level is opposite with the winding direction of even level.
Level is as shown in figure 10 in the past twined in the coil pipe 110, as shown in figure 14, utilizes the ETS method to pull out copper pipe from coil pipe, then as mentioned above, and the fractureing, be out of shape, cheat recessed and abrade of generating period.The result that the present inventor investigates its reason sees, level shown in Figure 10 is twined coil pipe equally make the vertical placement of its axle as shown in figure 14, then, when opening a book coil pipe, the hypomere tube portion of odd column breaks away from after the coil pipe inside, the hypomere tube portion of even column should break away from the inside of pipe, but the tube portion of the hypomere of this even column is sandwiched between the tube portion and side plate 102b of top of these row, is pushed to side plate 102a from the tube portion of top.Therefore, open a book when proceeding to the hypomere of this even column, to the very big resistance of copper pipe 101 effects, phenomenon like being plugged, pulling out needs big power, deforms once drawing reluctantly.
In contrast, among the present invention, level is twined coil pipe be placed on shelf, make the coil pipe axis normal, twine the beginning position up the time, after the decline of ground floor coil pipe was pulled up, second layer coil pipe was pulled up successively from its following position.At this moment, the hypomere tube portion of second layer coil pipe does not contact with shelf.Therefore, the hypomere tube portion (part that is drawn out at first) of this second layer coil pipe is not subjected to the constraint between the tube portion and shelf thereon, and pull out smoothly at the top of this second layer coil pipe, breaks away from the inside of coil pipe.
Like this, among the present invention, the tube portion bottom of odd column is drawn out, break away from after the coil pipe inner face, when the tube portion of the hypomere of even column will be pulled out, the tube portion of the hypomere of this even column does not contact with the side plate of coil pipe frame, is not subjected to the constraint in gap between tube portion on it and the shelf, and the tube portion of this even column is pulled out smoothly and broken away from the coil pipe inner face.Therefore, not generator tube fracture, be out of shape, cheat recessed and the scratch.
Also have, among the present invention, the writhing number of the coil pipe of odd-level is n, when the writhing number of the coil pipe of even level is (n+1), LWC is placed on shelf, make the axially vertical of coil pipe, twine the beginning position in following time, the coil pipe of the second layer is contacted with shelf at the tube portion of its hypomere, and be subjected to the tube portion of its epimere and the gap constraint between the shelf, but when pulling out pipe, when upwards pulled out the end that the ground floor coil pipe twines the pipe at beginning position (being positioned at the below), the part of pulling out at last of ground floor coil pipe was the tube portion of epimere, thereby the coil pipe of the second layer begins to pull out from the tube portion of epimere.Therefore, the coil pipe of the second layer is also pulled out smoothly.Though it pulls out the tube portion that top is hypomere the 3rd layer of coil pipe, gapped between the tube portion of its hypomere and the shelf, therefore, the 3rd layer of coil pipe also pulled out smoothly.Thus, not generator tube fracture, be out of shape, cheat recessed and the scratch.
Among the present invention, when the coil pipe writhing number of odd-level was identical with the coil pipe writhing number of even level, it was also passable to make the winding starting end be positioned at the below when LWC is contained in shelf.At this moment, be n at the tube portion of the hypomere of the pipe of odd column and even column and the coil pipe writhing number of odd-level, the coil pipe writhing number of even level is the identical arrangement of situation of (n+1), can pull out pipe equally.
In addition, relevant level of the present invention is twined in the coil pipe, the pipe location is twined and formation ground floor coil pipe, then, the coil pipe of the second layer is twined in the location on above-mentioned ground floor coil pipe, make the winding top of the coil pipe of its second layer be positioned at the outside of above-mentioned ground floor coil pipe last lap, the second circle pipe of the above-mentioned second layer is entrenched in the last lap of ground floor coil pipe and recess between the pipe of a circle before it; Later in the same way, the location is twined multilayer and is formed the multilayer coil pipe, the pipe writhing number of odd-level is identical with the pipe writhing number of even level, the coil pipe winding direction of odd-level is opposite with the coil pipe winding direction of even level, the number of plies be m (m is a natural number) cast out m/2 decimal point later on the value of rounding be m ', when the quality of coil pipe was W, W/m ' was less than 18.0kg.
Twine in the coil pipe in these levels, aforementioned tube is the compo pipe as copper or copper.
For example this level is twined coil pipe for what annealed, and on the section perpendicular to tube axial direction, the major diameter of copper or alloy copper pipe and the difference of minor axis are feature less than 0.2mm.
Also have, the chemical composition of copper pipe is the composition of JISC1201 or C1220 defined, and 0.2% yield strength is 65～130N/mm
2
In LWC110 as shown in figure 10 in the past, as shown in figure 14, utilize the ETS method when coil pipe is pulled out copper pipe, as mentioned above, the pipe of generating period fracture, be out of shape, cheat recessed and scratch.The present inventor investigates its reason and thinks: as shown in figure 14, place LWC110 shown in Figure 10, make the coil pipe axle vertical, when then opening a book coil pipe, the tube portion of the hypomere of odd column breaks away from after the coil pipe inner face, the tube portion that should be the hypomere of even column breaks away from the coil pipe inner face, but the tube portion of the hypomere of this even column is sandwiched between the copper pipe part and bolster of this side of listing, and is partly pushed to the below by the copper pipe of top.Therefore, when this thrust is big, when the work of pulling out proceeds to the hypomere of this even column, the resistance very big to the pulling action of copper pipe 110, the phenomenon that is plugged, thereby need big pullout forces, will deform if pull out reluctantly.
In contrast, among the present invention, make the given number of plies twining the number of plies, the increase of the above-mentioned clamping force of drawing up, the copper pipe of even column is pulled out smoothly, can break away from the coil pipe inner face smoothly.Therefore, not generator tube fracture, be out of shape, cheat recessed and the scratch.

The specific embodiment
Below, specify embodiment of the present invention in conjunction with the accompanying drawings.Fig. 1 is the profile that the level of the relevant embodiment of the present invention 1 of expression is twined the preparation method of coil pipe (following remember into LWC) 20, and Fig. 2 is the ideograph of this LWC first half of expression.Coil pipe frame 2 has inner core 2b cylindraceous and is installed in the side plate 2a at this inner core 2b both ends.Also have, this coil pipe frame 2 is installed on the rotating shaft of whirligig 103,104 of Fig. 5 or Fig. 6.In the present embodiment, at first make copper pipe 1 be positioned at the left end of inner core 2b, it as twining starting end 21, by whirligig 103,104 rotation driving-disc pipe supports 2, is wrapped in inner core 2b (vertically twining) to copper pipe 1 to the dextrad location of Fig. 1.That is, copper pipe 1 seamless unoccupied place between the copper pipe part always being located contiguously is wrapped on the inner core 2b.In the present embodiment, twine the ground floor coil pipe and finish, then the copper pipe of the terminal of ground floor part contacts with side plate 2a.Therefore, the axial length of inner core 2b is the integral multiple of copper pipe 1 external diameter, and the writhing number of supposing this ground floor coil pipe is that the external diameter of n, copper pipe 1 is D, and then, the length of inner core 2b is actually nD.When twining the end of ground floor coil pipe, twine the coil pipe of the second layer, make the copper pipe part 22 at its top be positioned at the ground floor coil pipe terminal (n circle) the copper pipe part and before it recess between copper pipe part of (n-1 circle), successively to the left-hand location winding of Fig. 1.The coil pipe of the second layer because do not enter the leeway outside the coil pipe between side plate 2a, carries out the 3rd layer winding under the state that stays the gap between the side plate 2a on the terminal of its left end.Thereby the coil pipe writhing number of the second layer lacks a circle than ground floor coil pipe writhing number, becomes the n-1 circle.The 3rd layer of n circle that coil pipe is identical with the ground floor coil pipe twines to the dextrad of Fig. 1.At this moment, the 3rd layer of coil pipe and ground floor coil pipe are same, and the copper pipe of its left end and right-hand member part is contacted with side plate 2a.The 4th layer identical with the second layer, makes the copper pipe part 23 at top gapped with side plate 2a, to the left-hand winding of Fig. 1.
Like this, can obtain LWC20, when the coil pipe writhing number of its odd-level was n, the coil pipe writhing number of even level was (n-1), and the coil pipe winding direction of the winding direction of the coil pipe of odd-level and even level is opposite.The LWC that makes like this takes out coil pipe frame and inner core after most external utilizes copper strips to carry out the anticreep processing, be annealed to the modifier treatment of wanting.If the LWC burn-back takes place during annealing, fracture when then utilizing the ETS method to open a book coil pipe, scar, distortion, the burn-back when pulling force, winding direction, stack direction and coil pipe writhing number, pipe oil outer, annealing temperature, annealing time and the anneal environment that therefore is necessary to select to twine coil pipe to avoid annealing.
Also have, burn-back does not take place in LWC, and for example material is under the situation of depickling copper, and 0.2% yield strength of the copper pipe after the annealing is 50～150N/mm
2, percentage elongation is 35～55%, when having the LWC of such yield strength and percentage elongation, bending that can generator tube, fracture, scar, can carry out the coil pipe of opening a book of ETS method described later.But this is an example, the invention is not restricted to have the LWC of such mechanical property.
Among the LWC20 of Gou Chenging, take out under the state of coil pipe frame 2 like this, shown in the ideograph of Fig. 3, place LWC20, make the axle of coil pipe vertical, twine starting end 21, up pull out top 21 last.At that rate, the coil pipe of the inner face of LWC20 (ground floor coil pipe) is opened a book and is broken away from the coil pipe inner face.So, the copper pipe of the hypomere (low order end among Fig. 1) of ground floor coil pipe partly breaks away from the coil pipe inner face, then the copper pipe part 22 at the winding top of the hypomere (low order end) of the coil pipe of the second layer should break away from the coil pipe inner face, but in the present embodiment, the copper pipe part 22 at this second layer top is not contacted with side plate 2a, and having the gap between the side plate 2a, copper pipe part 22 is not subjected to thereon the copper pipe part of layer (left) and the constraint of side plate 2a.Therefore, copper pipe part 22 breaks away from the inner face of coil pipe easily and successfully, pulls out smoothly from coil pipe 20.
Also have, the coil pipe writhing number of in the past each layer is identical n, but odd-level is that n, even level are n-1 in the present embodiment.The method of making between winding angle control method that the operation change of such LWC20 can be when changing vertical winding the and the change side plate 2a at interval is easy to realize.
In addition, in the present embodiment, the writhing number of LWC20 is that n, LWC quality are not subjected to particular constraints at ground floor coil pipe writhing number (odd-level).Generally, the ring layer number is 10～200 layers of degree, and each layer writhing number n is 10～100 circle degree, and the quality of LWC20 is 50～500kg degree.
As for the material of copper pipe, not special constraint.The present invention can be applicable to the coil pipe of the copper pipe that heat-transfer pipe, hot-water supply building pipe arrangement use or the coil pipe of alloy copper pipe well.The present invention is applicable to the copper alloy of phosphorized copper, Cu-Sn-P alloy (Cu-0.1～1.0Sn-0.01～0.05P etc.), Cu-Sn-Zn-P alloy (Cu-0.1～1.0Sn-0.1～1.0Zn-0.01～0.05P etc.) of fine copper, C1201, the C1220 etc. of C1020, C1100 etc. etc.
In addition, the size as for pipe has no particular limits.But if the thin thickness of pipe, then, twisting resistance during coil pipe of opening a book of back narration acts on pipe and goes up and easy deformation.Usually, external diameter is 4 to 25mm degree, and thickness is 0.15 to 1.5mm degree, and the value of (thickness of pipe/external diameter of pipe) is for well more than 0.03.
In addition, the modifier treatment as for pipe does not have specific restriction yet.During copper pipe, preferably be suitable for general soft material or semi-rigid material, but hard material can be suitable for also.Utilize hard material to make after the LWC anneal modified one-tenth soft material or semi-rigid material.
The packing method of relevant horizontal winding disc tube packaging body of the present invention then, is described.As shown in Figure 1, twine the coil pipe 20 of copper pipe 1, after, from inner core 2b dismounting side plate 2a, coil pipe frame 2 is taken out from coil pipe 20.Then, press the operation packing LWC20 shown in Fig. 4 (a) to (i) and Fig. 5 (a) to (f).
At first, shown in Fig. 4 (a), prepare shelf 11, shown in Fig. 4 (b), the thick polyethylene film plate 12 of wooden or resinous shelf 11 upper berths, 50 μ m.Then, shown in Fig. 4 (c), on polyethylene film plate 12, place thickness for example and be the cushion pad 13 that the polyethylene foam-material of 5mm is made, at this above cushion pad 13, shown in Fig. 4 (d), load the copper of taking-up coil pipe frame 2 or the coil pipe (LWC20) of alloy copper pipe 1, make it axially vertical.Then, to shown in Fig. 4 (i), circular ground paper disk 15 is an interlayer as Fig. 4 (e), piles up and adorns three layers of LWC20 (following copper or alloy brass pipe coil pipe three layers of accumulations calls three layers of coil pipe 16).Also place ground paper disk 15 above the LWC20 of epimere.These ground paper disks 15 become the cushion pad between the LWC20, the LWC20 during the protection transportation.
Secondly, shown in Fig. 5 (a), for example, be thickness that the sack 17 of the polyethylene film system of 50 μ m is worn on three layers of coil pipe 16, cover three layers of coil pipe 16.Also have, shown in Fig. 5 (b), the protection when forming the packing that elongated corrugated paper makes cushions paperboard strip 18, is close to three layers of coil pipe 16 periphery to shelf above three layers of coil pipe 16; Shown in Fig. 5 (c) and figure (d), be fixed on this buffering paper slip 18 above three layers of coil pipe 16 and the top of shelf 11.At this moment, for example utilize on three layers of coil pipe 16 top that tab 19a fixes, utilize stapler 19b to fix on shelf 11 tops.
Then, shown in Fig. 5 (e), for example preparing width is that 500mm, thickness are the banded resin band 14 of the polyethylene film system of 25 μ m, keeps the stretched condition of this resin band 14, rolling up from top to bottom around three layers of coil pipe 16, also shelf 11 an also roll set.
Then, shown in Fig. 5 (f), utilize from the lower to the upper once more around three layers of coil pipe 16 of resin band 14 bundles of stretched condition.Thus, three layers of coil pipe 16 and shelf 11 are together by twice resin band 14 tension packing.At this moment, resin band 14 being applied the pulling force that extends two double-length degree ties.So the width of resin band 14 becomes original 70～80% substantially.
Like this, utilize three layers of coil pipe 16 and shelf 11 sack 17 of polyethylene film manufacturing and resin band 14 to carry out the hard-pressed bale dress together, therefore three layers of coil pipe 16 almost completely seal.
Also have, when unpacking, resin band 14 is cut off by cropper (scissors) on the surface of buffering paperboard strip 18, because there is buffering paperboard strip 18 can not accidentally injure three layers of coil pipe 16.
Also have, the sack 17 and the resin band 14 that cover three layers of coil pipe 16 outer surface can use polythene material to make.Though resin has a water penetration, the method that is twined by multilayer can prevent that moisture from entering coil pipe inside, preventing variable color.Also have, the thickness of resin band is not had specific restriction, but select that 10～100 μ m's is just passable.General 30～70 μ m that use are for well.In order to improve sealing effectiveness volume multilayer for well.
Also have, pack between shelf 11 and the coil pipe 20 bolster 13 and pile up when loading coil pipe 20 interlayer with the ground paper disk 15 of bolster, the thing that can use polyethylene foamed to make, but when not having the inner variable color of coil pipe dangerous, also can use the corrugated paper material.Also have, the external environment condition dew point when preferably packing LWC20 is low, the dew point during packing below 22 ℃ for well.
Also have, as required LWC20 is fixed on shelf 11, in order to avoid rock during transportation.For example, central part level altitude on four limits of shelf 11 equals the wooden post of the LWC20 of the superiors upper surface, and relative above-mentioned wooden post upper end utilizes wood-block with cross fixing and strengthen, from the shelf bottom to the LWC of the superiors upper surface with iron band tie tight pillar and wood-block.Under this state, below shelf, utilize multi-layer resinous band to strain packing to the superiors' LWC upper surface, make atmosphere be not easy to enter coil pipe inside.
As mentioned above, because LWC20 (three layers of coil pipe 16) is utilized resin band 14 tension packings, moisture enters the inside of coil pipe 20 in can preventing to take care of and transport, and can prevent coil pipe generation variable color.
LWC20 opens a book, copper pipe 1 is without interruption when giving the place to use, at first, shown in Fig. 5 (f), packaged three layers of coil pipe 16 are placed on the place to use by previous status, buffering paperboard strip 18 is a lining shelves material, cut off resin band 14 with cropper, the paperboard strip 18 of dismounting buffering then, again after, shed sack 17, the three layers of coil pipe 16 of unpacking.
Thereafter, same as Figure 14, control the winding starting end 21 of LWC20, promote toward the top, by guide pipe 115 copper pipe 1 is fed to the place to use.So, as mentioned above, from the inner face of coil pipe 20 copper pipe 1 that begins to open a book, the coil pipe of dual numbers layer, whole coil pipes of odd-level and even level are not subjected to the constraint of its upper copper tube portion and side plate 2a in its copper pipe part 22 of opening a book at first, so can successfully be opened a book from coil pipe 20.After the LWC of the superiors opened a book, same, the LWC of the hypomere of the second layer began to open a book.
Also have, if not packed state as shown in Figure 4 and Figure 5, when transportation and keeping, that is, for example, LWC is equipped with the state keeping and the transportation down of coil pipe frame, when opening a book LWC, is necessary to take out earlier the coil pipe frame., at this moment, need to take out the time of inner core 2b and side plate 2a, therefore, as shown in Figure 4 and Figure 5, preferably not under the state of tep reel pipe support, a plurality of LWC20 are placed on shelf 11 pack afterwards.Like this, the following packing LWC20 of tep reel pipe support state as long as unpack in the place to use, is placed on the LWC that can open a book under the state of shelf.In addition, guide pipe 115 is not limited to the tubular part of break-through copper pipe, also can utilize the parts of roller shape.
In addition, packing method as shown in Figure 4 and Figure 5 is not only applicable to embodiment 1, is applicable to the embodiment 4 of following narration yet.
Below, the LWC30 of the relevant embodiment of the invention 2 is described.Fig. 6 is the ideograph that the LWC30 of the present embodiment 2 is made in expression.Fig. 7 is the open a book ideograph of method of this LWC30 of expression.In the present embodiment, as shown in Figure 6, begin the location from the winding starting end 31 of ground floor coil pipe and twine after the n circle, the slit lining between the tube portion of the last lap of ground floor and the side plate 2a is put the tube portion at second layer top, location winding second layer coil pipe.So, the tube portion of the terminal of this second layer coil pipe is arranged between the tube portion and side plate 2a at ground floor coil pipe top, then, it is chimeric the 3rd layer of coil pipe location to be wrapped between the pipe of the second layer coil pipe recess.Therefore, the writhing number of supposing the ground floor coil pipe is n, and then the writhing number of second layer coil pipe is n+1, and the writhing number of second layer coil pipe is n, and the odd-level writhing number is the n circle, and the even level writhing number is that twine the location of n+1 circle.Also have, between the side plate 2a setting benchmark of distance be external diameter of pipe (n+1) doubly.
Among the LWC30 of Gou Chenging, as shown in Figure 7, make winding top 31 be positioned at the below like this, the axle of coil pipe vertically is placed on the shelf.Also have, up pull out from twining top 31, then, as shown by arrows, up pull out the ground floor coil pipe successively from the bottom, after its epimere tube portion was opened a book, the epimere tube portion of the second layer was drawn out.So the coil pipe of the second layer is pulled out toward the below successively from the top.After the hypomere of second layer coil pipe was drawn out, the hypomere tube portion of the 3rd layer of coil pipe was drawn out, but the hypomere tube portion of this 3rd layer of coil pipe because and have the gap between the shelf, unfettered.Therefore, the 3rd layer of coil pipe also pulled out smoothly.Like this, the LWC of present embodiment can pull out copper pipe smoothly.
The following describes the LWC40 of relevant embodiment of the present invention 3.Fig. 8 is the ideograph that the LWC40 method of the present embodiment 3 is made in expression, and Fig. 9 is the open a book ideograph of method of this LWC40 of expression.In the present embodiment, as shown in Figure 8, the n circle is twined in ground floor coil pipe location, and the tube portion at the top of second layer coil pipe is arranged between the tube portion and its winding (n-1 circle) tube portion before of last winding (n circle) of ground floor coil pipe, after, second layer coil pipe is twined in the location.Also have, the tube portion of the terminal of second layer coil pipe is arranged between the tube portion and side plate 2a at top of ground floor coil pipe, finishes the location winding of second layer coil pipe.Then, the tube portion at the top of the 3rd layer, the 4th layer coil pipe is arranged in down between the tube portion at top of one deck coil pipe and next the circle tube portion location and twines the n circle.In the present embodiment, the coil pipe writhing number of odd-level and even level is the n circle.
Among the LWC40 of the embodiment 3 of Gou Chenging, LWC40 is placed on the shelf like this, makes and twine top 41 last.Also up pull out tube portion from twining top 41 beginnings.So, be pulled out to after the ground floor coil pipe of hypomere, should draw the second layer, but its second layer tube portion of pulling out at first is at hypomere, gapped between this hypomere tube portion and the shelf, therefore break away from easily, pull out smoothly.Like this, in the present embodiment, equally also can pull out pipe smoothly.
In the present embodiment, also can be placed on shelf to LWC, make twine top 41 below.At this moment, the tube portion of the hypomere of odd column and even column since with the relation of shelf, as shown in Figure 6 and Figure 7 and the same arrangement of hypomere tube portion of embodiment 2.Therefore, in the present embodiment 3, also twining top 41 following, the ground floor coil pipe is up pulled out successively from the below, then second layer coil pipe is down pulled out successively from the top, this second layer coil pipe is pulled out when arriving its hypomere, and is gapped between the tube portion of the hypomere of the 3rd layer of coil pipe and the shelf, also can pull out the 3rd layer of coil pipe smoothly.Therefore, among the LWC of embodiment 3, also can twine top 41 to it and be placed on shelf lastly, also can twine top 41 to it and be placed on shelf down.
Below, embodiment of the present invention 4 are described.In the present embodiment, the same winding method of conventional art shown in Figure 10 forms the coil pipe that only twines the m layer.Promptly, the location is twined and is formed after the ground floor coil pipe, at this above ground floor coil pipe, second layer coil pipe is twined in the location, make second layer coil pipe be entrenched in the whole of recess between ground floor coil pipe outermost tube, after, same method location is twined multilayer and is formed the multilayer coil pipe, the writhing number of the writhing number of the pipe of odd-level and the pipe of even level equates that the coil pipe winding direction of the winding direction of the coil pipe of odd-level and even level is opposite.Here, open a book smoothly, twine in the number of stories m in order to utilize the ETS method, suppose the number of plies of the even level of support coil pipe weight, promptly the later integer of m/2 fractions omitted point is m ', and the quality of making the employed copper pipe of LWC is W[kg], then, must satisfy W/m ' 18.0kg.This is because if W/m ' surpasses 18.0kg, the burn-back of copper pipe takes place when then LWC anneals easily, even burn-back does not take place, place coil pipe, make it axially vertical, make and twine top last, when carrying out by the opening a book of ETS method, the fractureing of copper pipe, crooked, abrasive cause take place greatly and easily in the pressure that acts on the copper pipe of the hypomere of even level.Also have, in order more successfully to carry out opening a book of ETS method, preferably W/m '≤16.0kg.
Like this, the winding number of turns that can be made into the coil pipe of hypothesis odd-level is n, and then the winding writhing number of even level coil pipe also is n, and the volume number of plies that the winding direction of the winding direction of the coil pipe of odd-level and even level coil pipe is opposite is the LWC20 of m.The LWC of Zhi Zuoing like this utilizes copper strips to carry out taking out coil pipe frame and inner core after anticreep handles in outermost, carries out the annealing of institute's pacemaker.
When making LWC, because apply winding copper pipe under the state of pulling force, the copper pipe section configuration becomes the ellipse that dwindles towards the extending axially of inner core, towards the winding layer direction.If the difference between this oval major diameter and the minor axis surpasses 0.2mm, when then annealing, burn-back takes place easily, reduce the yield rate of LWC.Also have, when utilizing the ETS method to open a book, become the distortion of copper pipe, abrasive reason.Therefore, perpendicular to pipe the axle section on, the major diameter of copper pipe and the difference of minor axis are preferably below the 0.2mm.Also have, the major diameter of section and the mensuration of minor axis are that the copper pipe that the first lap of the LWC after annealing is pulled out carries out just passable.And the difference of above-mentioned major diameter and minor axis is preferably below the 0.15mm.
And then, in order to prevent burn-back, be necessary suitably to select tube outside oil, annealing temperature, annealing time and annealing atmosphere.
Also have, do not allow the material of burn-back that LWC takes place, for example, when its material was C1201, C1220, preferably 0.2% yield strength of the copper pipe after the annealing was 65～130N/mm
2Yield strength after the annealing is in the above-mentioned scope time, bending that can generator tube, fracture, scar, as described later, can utilize opening a book of ETS method.If 0.2% yield strength is less than 65N/mm
2The time, when utilizing the opening a book of ETS method, the bending of generator tube and fractureing easily is if 0.2% yield strength is above 130N/mm
2The time, when utilizing the opening a book of ETS method, the rollback resistance is big, and, because the folding line of copper pipe takes place in the sclerosis that processing causes and the yield strength of copper pipe also increases easily during the assembled heat interchanger.
Also have, satisfy beyond the above-mentioned yield strength, also satisfied 0.2% yield strength/tensile strength values is 0.30～0.40, and percentage elongation is 45～55% o'clock, is more suitable in utilizing opening a book of ETS method.
Among the LWC20 of Gou Chenging, take out under the state of coil pipe frame like this, same as Figure 14, place LWC20, make its coil pipe axle vertical, make and twine top 21 last, up pull out top 21.So the coil pipe of the inner face of LWC20 (ground floor coil pipe) is opened a book, and breaks away from from the coil pipe inner face.So, the copper pipe part of hypomere (Fig. 1 low order end) that should be the ground floor coil pipe is when the coil pipe inner face breaks away from, the copper pipe part 22 at the winding top of (low order end) bottom of second layer coil pipe breaks away from from the coil pipe inner face, but in the present embodiment, copper pipe part 22 contact at this second layer top is at buffer unit etc., the copper pipe that is subjected to its upper strata (left) partly and between the buffer unit retrains, but the ratio of LWC quality and winding layer is below 0.9kg, so, copper pipe part 22 breaks away from the coil pipe inner face easily and successfully, pulls out smoothly from coil pipe 20.
Also have, in the present embodiment, also the same with in the past, the writhing number of each layer is n, so there is no need to change operation (distance changes between the change of the winding angle control method when vertically twining and the side plate 2a) in order to make such LWC20.
In addition, the present embodiment is applicable to that the coil pipe quality of LWC20 is 50 to 500kg, the W/m ' of above-mentioned quality (m ' be the later integer of m/2 fractions omitted point) below 18.0kg, decide m just passable.Also have the writhing number n of each layer not have specific restriction, but be generally the degree of 10～100 circles.
