Harness silk 3a～3d uses the label line (silk after the piano wire annealing) of φ 1.4mm.This material bends (plastic deformation) easily, and pulling strengrth is little, and elongation is also bigger.But be the occasion that rectangular coil 1 carries out harness with the coil section, using the material of this easy bending (plastic deformation), can avoid the angle of this coil section to become circle, so this material is suitable for being harness silk 3a～3d (seeing Table 1).After using this material, shown in Fig. 3 a and 3b, after node was made in the top 3cs of harness silk 3c and terminal 3ce bending, this node can bear the tensile force of 10kgf at least.The end of other harness silk 3a, 3b and 3d also is connected with connecting filament 2 with the same manner.

Fig. 5 represents the coil 1 of the 2nd embodiment.The welding wire reeling shape of coil 1 is with shown in Figure 1 identical, just the amount of about 1 circle of its coil terminal portion, be that the final coiling circle 1e of welding wire uses as connecting filament.The cylindric coiler part of coil 1 is carried out harness at 4 positions with harness silk 3a～3d with the interval of about 90 degree.Used identical of the material that uses as the harness silk and coil shown in Figure 11.Behind harness, the cylinder end that is in innermost layer, the coiling initiating terminal 1s that becomes the circle end of reeling at first to the radial direction bending of the circle of reeling with as radial direction limit 1sr, then roughly half part of its most advanced and sophisticated side roughly with coil axes abreast in coil lateral buckling like this coiling initiating terminal 1s is made hook-type with as an axle parallel edges 1sa.

Fig. 6 amplifies the node of the point of expression connecting filament (the final coiling circle of welding wire) 1e shown in Figure 5.Be to be turned back in harness silk 3a two ends, clamp so that before the end of connecting filament 1e and its 1 circle that enclosed both, and the end of connection lead 1e is turned back with the state of clamping harness silk 3a, therefrom the end of connecting filament 1e and harness silk 3a are fastened.The U font is turned back at the two ends of harness silk 3a respectively, interlinks simultaneously.

Fig. 7 a, 7b represent the connection of harness silk 3d on connecting filament 1e.Turning back with the state of clamping connecting filament 1e in the two ends of this harness silk 3d, comes like this to combine with connecting filament 1e.The U font is turned back at the two ends of harness silk 3d respectively, interlinks simultaneously.Other harness silk 3b, 3c also uses with the same method of attachment of 3d and combines with connecting filament 1e.

When Fig. 8 represents the final coiling circle 1e of welding wire used as connecting filament, the fixing bundling method variation of the harness silk 3a of usefulness of the terminal part of the circle 1e that will finally reel.In this deformation form, most advanced and sophisticated 3as, the 3ae of harness silk 3a bipod to link between the tip and to be that the center is done 180 ° and rotated and turn back with the perpendicular line around connecting filament 1e, are so just enclosed the curve of formation S font final the coiling on the outer peripheral face of coil 1.Curve with this S font makes final coiling circle 1e engage mutually with harness silk 3a, so needn't form the L font kink (Fig. 6) of engaging usefulness again at final end of reeling circle 1e.In addition, when carrying out the harness operation of harness silk 3a, when final coiling circle is difficult to bend to the S font, can be before harness silk 3a be carried out harness, the end at the final circle of reeling forms S oxbow portion in advance.

Fig. 9 a represents to be equipped with the packing chest elevation profile of the 1st form of above-mentioned coil 1, and Fig. 9 b represents the bench section.The coil 1 that does not have reels such as spool on end (coil axes is horizontal y direction) is put into corrugated board packing chest 21.Transport after when needing a plurality of packing chests 21 that coil 1 is housed being piled up in freight container.The upper side of outer container 21b that constitutes packing chest 21 is being that hinge becomes lid to be opened/closed with one side that vertical horizontal side 21s3 (or 21s4) joins.The shape that coil 1 is made after by harness line 3a～3d harness is cylindric (circular, but section is square), its periphery and outer container bottom surface are tangent, so move (rotation) to the x direction easily.In the be moved occasion of (rotation) of coil 1, collide with the vertical side 21s1 of outer container 21b and 21s2 easily and cause breakage, or coil 1 deforms with other object collisions across vertical side 21s1,21s2.

To on the 21bm of the bottom surface of outer container 21b, dispose the anti-movable block 21b1 and the 21b2 of corrugated board system for this reason.The zx section of anti-movable block 21b1 and 21b2 is a triangle, the length of length direction (y direction) and the depth of outer container 21b, is the interior depth consistent size of case of bottom surface 21bm.These anti-movable block 21b1 and 21b2 are laid on the base plate 21p of corrugated board system.The size of base plate 21p is consistent with the case inside dimension of the bottom surface 21bm of outer container 21b, thereby piece 21b1,21b2 and base plate 21p embed the bottom surface of outer container 21b, can not move.

The direction of the formed leg-of-mutton limit b1a of piece 21b1 is towards the center C R of coil 1, and the direction of the formed leg-of-mutton limit b1b of piece 21b1 is consistent with the periphery tangent line a of coil 1.The direction of the formed leg-of-mutton limit b2a of piece 21b2 is towards the center C R of coil 1, and the direction of the formed leg-of-mutton limit b2b of piece 21b2 is consistent with the periphery tangential direction b of coil 1.

Piece 21b1,21b2 and the outer peripheral face position contacting of coil 1 are chosen in height (z) direction that the lower position of coil 1 just contacts with base plate 21p, so coil 1 is supported on 3 points, the weight loading that imposes on packing chest 21 is dispersed, and can not rocks.The outer peripheral face position contacting of piece 21b1,21b2 and coil 1 also can be chosen in the lower position of coil 1 and the height (z direction) that base plate 21p disengages.Because coil 1 obtained unsettled supporting by piece 21b1 and 21b2 on 2 o'clock, so stability is high.Pushing block 21b1,21b2 because the compression strength of piece 21b1 and 21b2 is very big, so can not deform, can prevent to move effectively even coil 1 will move (rotation) to the x direction.

This anti-movable block 21b1,21b2 are corrugated board systems, and low price and deal are light, easily processing.All use corrugated board system owing to comprise the packing chest 21 of anti-movable block 21b1,21b2, so, especially do not have problem even also can be used as trade waste when passing into disuse.

Figure 10 a and Figure 10 b are the elevation profile and the bench section of the packing chest of the 2nd form.Outer container 21b and aforesaid the 1st homomorphosis, just anti-movable block 21b1,21b2 difference.Anti-movable block 21b1, the 21b2 of the 2nd form and base plate 21b make with 1 elongated corrugated board bending, its depth (y direction length) and the interior depth consistent size of the case of the bottom surface 21bm of outer container 21.Both ends with elongated corrugated board are bent into spiral type exactly, so that section becomes triangle, make anti-movable block 21b1 and 21b2 like this.The direction of the formed limit b1c of terminal part of the direction of the formed leg-of-mutton limit b1a of piece 21b1 and corrugated board is towards the center C R of coil 1, and the direction of the formed leg-of-mutton limit b1b of piece 21b1 is consistent with the periphery tangent line a of coil 1.

The direction of the formed limit b2c of terminal part of the direction of the formed leg-of-mutton limit b2a of piece 21b2 and corrugated board is towards the center C R of coil 1, and the direction of the formed leg-of-mutton limit b2b of piece 21b2 is consistent with the periphery tangential direction b of coil 1.

The size on the plane of the connecting bridge of anti-movable block 21b1,21b2 and two pieces is consistent with the case inside dimension of the bottom surface 21bm of outer container 21b.Thereby the connecting bridge of piece 21b1,21b2 and two pieces embeds the bottom surface of outer container 21b, can not move.

Piece 21b1,21b2 and the outer peripheral face position contacting of coil 1 are chosen in height (z) direction that the lower position of coil 1 just contacts with base plate 21p, so coil 1 is supported on 3 points, the weight loading that imposes on packing chest 21 is dispersed, and does not have and rock.The outer peripheral face position contacting of piece 21b1,21b2 and coil 1 also can be chosen in the lower position of coil 1 and the height (z direction) that base plate 21p disengages.Because coil 1 obtained unsettled supporting by piece 21b1 and 21b2 on 2 o'clock, so the stability height.The anti-formed leg-of-mutton limit of movable block 21b1,21b2 is double-decker except limit b1b, b2b, and compression strength is very big, so can not deform.The direction of the anti-formed leg-of-mutton limit b1b of movable block 21b1,21b2, b2b and the periphery tangential direction of coil 1 are same direction, when coil 1 will move (rotation) to the x direction, can prevent effectively that it from moving.

Figure 11 a and 11b are the longitudinal section and the sectional elevations of the packing chest of the 3rd form.Outer container 21b and the aforesaid the 1st and the 2nd homomorphosis, but prevent movable block 21b1,21b2 difference.Anti-movable block 21b1, the 21b2 of the 3rd form and base plate 21p make with 1 elongated corrugated board bending, the width of its depth (y direction length) and outer container 21b, are that the case inside dimension of vertical side 21s1,21s2 is consistent.End with elongated corrugated board is bent into spiral type exactly, so that the xz section becomes the double-ply triangle, makes anti-movable block 21b1 and 21b2 like this.Piece 21b1 is made of the big triangle t1 in the outside and inboard little triangle t2, and the big triangle t1 in the outside forms on one side and to connect in the vertical side 21s1 with outer container 21b and extend, connect and along the x direction is extended, the periphery tangent line of another side b1b and coil 1 joins and extends right-angled triangle on one side with in the 21bm of bottom surface along the z direction.The direction of the limit b1a of inboard little triangle t2 is towards the center C R of coil 1, and connects in limit b1d and the limit b1b.

Piece 21b2 is made of the big triangle t3 in the outside and inboard little triangle t4 in addition, and the big triangle t3 in the outside forms on one side and to connect in the vertical side 21s2 with outer container 21b and extend, connect and along the x direction is extended, the periphery tangent line of another side b2b and coil 1 joins and extends right-angled triangle on one side with in the 21bm of bottom surface along the z direction.The direction of the limit b2a of inboard little triangle t4 is towards the center C R of coil 1, and connects in limit b2d and the limit b2b.

The size on the plane of anti-movable block 21b1 and 21b2 is consistent with the case inside dimension of the bottom surface 21bm of outer container 21b.Thereby the connecting bridge of piece 21b1,21b2 and two pieces embeds the bottom surface of outer container 21b, can not move.

Piece 21b1,21b2 and the outer peripheral face position contacting of coil 1 are chosen in the height (z direction) that the lower position of coil 1 just contacts with base plate 21p, so coil 1 is supported on 3 points, the weight loading that imposes on packing chest 21 is dispersed, and does not have and rock.The outer peripheral face position contacting of piece 21b1,21b2 and coil 1 also can be chosen in the lower position of coil 1 and the height (z direction) that base plate 21p disengages.Because coil 1 obtained unsettled supporting by piece 21b1 and 21b2 on 2 o'clock, so the stability height.Pushing block 21b1,21b2 because the compression strength of piece 21b1,21b2 is very big, so can not deform, can prevent to move effectively even coil 1 will move (rotation) to the x direction.

But, more than Shuo Ming packing chest all is a packing chest of only adorning 1 coil 1, and as long as packing chest 21 and piece 21b1,21b2 along the prolongation of y direction, just can be a plurality of coils with the form of lining up 1 cylinder packing chest of packing into.In this occasion, packing chest is decided according to what coils of will packing into altogether in the length of y direction.

Figure 12 a is that Figure 12 b is its sectional elevation pack into the longitudinal section of an example of a big packing chest 27 of the packing chest 23～26 that 5 coils 1 respectively are housed.
