Description

  The present invention relates to a package structure for level-wound coils, and more particularly to a package for level-wound coils having a structure in which a plurality of level-wound coils are stacked on a cardboard pallet.

  Conventionally, copper pipes made of copper or copper alloys have been used as heat transfer pipes such as smooth pipes and internally grooved pipes in air conditioning equipment such as air conditioners, and as hot water supply pipes and water supply pipes for construction. These copper tubes and the like are generally wound in a coiled form called a level wound coil (hereinafter abbreviated as LWC) in the manufacturing process, and then subjected to a predetermined tempering by annealing. After being applied, it is packaged, transported and shipped to air conditioner manufacturers, etc., and air conditioner manufacturers unpack it, unroll copper pipes, etc. and use them for their respective purposes. ing.

  In this regard, such an LWC is formed by, for example, arranging a tube body such as a copper tube around a bobbin in a plurality of layers (rows) as shown in FIGS. 1 and 2 of Japanese Patent Application Laid-Open No. 2010-1072 (Patent Document 1). ) In the form of layer). More specifically, a bobbin composed of a removable inner cylinder and a side plate is attached to a predetermined rotating device so that its axial direction is horizontal or vertical, and is driven to rotate. First, a first coil layer having a cylindrical shape is formed on the outer peripheral surface of the inner cylinder, with the position on one end side in the bobbin axial direction being the starting end and aligned winding toward the opposite end. Then, after the tube has come to the opposite end and the winding of the first layer is finished, the second coil layer is aligned from the opposite end to the starting end. In this case, the second-layer tube portion is 1 so that it fits into a recess formed between adjacent tube portions in the first coil layer. The second coil layer is formed so as to be in close contact with each other on the coil layer, and the second coil layer is formed. Thereafter, the tube is aligned and wound in the opposite direction, and the third layer is wound. The LWC is formed by a so-called traverse winding method in which a coil layer is formed and subsequently wound in the same manner and a plurality of coil layers are laminated.

  The LWC thus obtained is then removed from the bobbin (inner cylinder + side plate), and in the form of a wound body of the tubular body, as shown in FIG. Plural pieces are stacked coaxially in the vertical direction to form a package, and the obtained package is transported and shipped to an air conditioner manufacturer or the like.

  Incidentally, as one of such LWC packing bodies, in Japanese Utility Model Publication No. 2-33564 (Patent Document 2), Japanese Utility Model Publication No. 4-91891 (Patent Document 3), etc., a cardboard pad or cardboard The package structure of LWC using packing materials such as a cylinder and sheet-like cardboard has been clarified. There, a packaging structure is adopted in which a support member is erected on the side surface of a plurality of LWCs stacked on a wooden pallet and the vicinity thereof is bound with a steel band. When transporting a plurality of packing bodies stacked in the vertical direction, the steel band tends to loosen, which may cause the position of the support member to move, and the pallet that supports the weight of the packing body Since it is made of wood, the weight is heavy, and the physical burden on the packaging operator is large, so that weight reduction is desired.

  On the other hand, as one of pallets for supporting a load, Japanese Utility Model Publication No. 62-146731 (Patent Document 4) discloses a pallet structure formed of cardboard, thereby reducing the weight. However, when a similar package is further stacked on a package obtained by laminating LWC using such a corrugated cardboard pallet, the package at the top of the package is obtained. Since the weight of the pallet can act directly or indirectly on the cardboard pallet of the lower package, such pallets present strength problems and therefore stack such packages. It was difficult to do.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

  First, FIG. 1 schematically shows a packaging assembly obtained by removing a resin film in an example of an LWC packaging structure according to the present invention. In this case, the LWC packaging assembly 10 is made of a cardboard pallet 12, three LWCs 14 concentrically stacked thereon, and arranged on both upper and lower sides of each of the LWCs 14. An upper holding plate 16a, intermediate holding plates 16b and 16b, a lower holding plate 16c, a cross-shaped canopy member 18 disposed on the upper holding plate 16a, and four ends of the canopy member 18 It is comprised from the four support | pillar 20 which each supports.

  Specifically, a cardboard pallet 12 which is one member constituting the packaging assembly 10 is a cardboard board having a rectangular shape as a whole, for example, a three-layer structure, as shown in FIG. It has an upper surface plate 22 made of corrugated cardboard with an appropriate number of layers. On the lower surface of the top plate 22, four cardboard L-shaped girders 24 and four cardboard rectangular girders 26 are fixed at the same height as legs. Yes. That is, as shown in FIG. 2A, the four L-shaped girders 24 have the L-shaped inner corners toward the corners at the four corners of the rectangular upper surface plate 22, and thus the outer sides. The four rectangular girders 26 are provided at the center of each side of the rectangular upper surface plate 22 and have a notch recess 28 with a predetermined depth. Each is disposed so as to be located inward. As a result, the L-shaped beam member 24 and the rectangular beam member 26 are arranged on either side of the upper surface plate 22 with a space in which the forklift and the fork can be inserted. Further, as will be described later, the notch recess 28 has a side opening so that the support 20 is fitted and held from the side when the support 20 is erected. , Provided. Furthermore, the notch recess 28 holding such a support | pillar 20 can be easily formed now only by giving a cutting process with respect to the upper surface board 22. FIG.

  Then, a cardboard pallet 12 like this is used, and a plurality of, for example, 2 to 4 (here, 3) LWCs 14 are stacked thereon to form a packaging assembly 10 as shown in FIG. 3, the lower holding plate 16c, one LWC 14, the intermediate holding plate 16b, one LWC 14, and the intermediate holding plate 16b, and one piece are placed on the pallet 12, as shown in FIG. The LWCs 14 are sequentially stacked, and then the upper holding plate 16a is placed on the uppermost LWC 14, and then a cross-shaped wooden canopy member 18 is placed on the upper holding plate 16a. The four plate-like struts 20 are erected and assembled so as to support the two end portions in a state of being fitted into the rectangular cutout recess 28 of the pallet 12. That process is employed, thereby, is of the fact that the packing assembly 10 of interest is produced.

  Here, the plurality of LWCs 14 to be stacked are a plurality of coil layers formed by aligning and winding a tubular body such as a copper tube, and a tubular body of one adjacent coil layer is a tubular body of the other coil layer. It has a known structure that is laminated so as to be fitted in the recesses between them. Such an LWC 14 is formed by removing the bobbin after the tube body is wound around the bobbin by a normal aligned winding method, for example, by traverse winding as illustrated in Patent Document 1 described above. It is what has been. Such LWC 14 generally has dimensions of an outer diameter of about 800 to 1000 mm and a width of about 200 to 400 mm, and its weight is about 100 to 300 kg.

  Further, the upper holding plate 16a, the intermediate holding plate 16b, and the lower holding plate 16c arranged above and below each of the LWCs 14 are for protecting each LWC 14, and are preferably made of cardboard. In general, a corrugated cardboard having a thickness of about 5 to 20 mm is used, and one having a size or diameter larger than the outer diameter of the LWC 14 is used. In particular, it is desirable that the upper holding plate 16a and the intermediate holding plate 16b have a circular shape, and the diameter of the upper holding plate 16a and the intermediate holding plate 16b is the corresponding notch recesses 28, 28 provided in the top plate 22 of the pallet 12. It is desirable to be configured to be substantially equal to the distance between them. The lower holding plate 16c may have a circular shape or a rectangular shape, but the size thereof is substantially the same as the diameter of the upper holding plate 16a or the intermediate holding plate 16b. . By using the upper, middle, and lower holding plates 16a, 16b, and 16c having such a size, it is possible to effectively suppress or prevent the support column 20 from directly contacting the LWC 14.

  Further, here, the canopy member 18 is formed of a wooden plate material as a cross-shaped integrated member, and the four end portions of the cross-shaped are abutted and supported by the support columns 20 respectively. It has become so. That is, the canopy member 18 protrudes from the LWC 14 in the diameter direction of the LWC 14 (larger than the outer diameter of the LWC 14), and further protrudes outward from the upper holding plate 16a. It is composed of a long plate 18a and two short wooden plates 18b and 18b having a predetermined width which are attached to the long wooden plate 18a to give a similar length. Specifically, the two short plates 18b and 18b are fixed to the both sides of the central portion of the long plate 18a by metal fittings 18c and 18c, respectively, so that an integral cross-shaped member is obtained. It is configured as.

  In such a cross-shaped canopy member 18, four struts 20 made of a wooden plate having a predetermined width are provided in the notch recesses of the pallet 12 in order to abut and support the four ends. In the form of being fitted and accommodated in 28, it is erected and assembled. The support column 20 is made of wood here, but it is a rigid member made of other material such as a lightweight metal as long as it has sufficient strength to support the load transmitted from the canopy member 18. Even if it exists, even if it exists, it can be comprised with columnar materials of various cross-sectional shapes, such as prismatic column shape and a column shape other than plate shape.

  Further, as shown in FIG. 4, the support column 20 does not substantially transmit the load applied via the canopy member 18 to the pallet 12, as shown in FIG. 4, the pallet 12, the three LWCs 14, and the four holding plates 16 a and 16 b. , 16b, and 16c, the load acting on the canopy member 18 is mainly transmitted to the four support columns 20, and the pallet 12, and thus for packing. The assembly body 10 is directly supported by the placement surface 30 on which the assembly 10 is placed. As a result, the three LWCs 14 stacked on the pallet 12 are connected to the LWC 14 from the canopy member 18. Loads that cause problems are virtually inoperative.

  Furthermore, the size of the rectangular notch recess 28 opened to the side in the pallet 12 is substantially the same as the cross-sectional shape of the support column 20, and the support column 20 fitted into the notch recess 28 is illustrated in FIG. As shown in FIG. 5, it is fitted so that there is no gap (play), and can be firmly held on the pallet 12, and the outer side surface of the support column 20 is connected to the top plate 22 of the pallet 12. The outer peripheral surface is flush with the outer peripheral surface so as not to protrude outward. Further, the diameters of the four holding plates 16a to 16c are substantially equal to the distance between the corresponding notch recesses 28 and 28 in the upper surface plate 22, so that the four support columns 20 have the holding plates 16a. By 16c, it is set as the form which is supported from the inside, and the fall to the assembly body 10 for packing can be prevented now.

  The packaging assembly 10 having such a configuration is made into an integral packaging body 32 having a packaging form as shown in FIG. 6 by packaging using an appropriate resin film. Here, as the resin film 34 for packing the packing body 32 of the LWC 14, a shrinkable resin film that can be shrunk by heat or the like, conventionally used for packing or packaging, a stretchable resin film, or the like Is used as appropriate, and the pallet 12, the LWC 14, the holding plates 16a to 16c, the canopy member 18, and the support columns 20 are integrally tightened with a resin film to form a packing structure. The strut 20 can be held more firmly.

  In addition, as such a resin film 34, an elastic band-shaped resin film made of a resin such as polyethylene is used, and at least the side surface of the packaging assembly 10 is stacked while maintaining the stretched state of such a resin film. The side surfaces of the three LWCs 14, the four struts 20, the side portions of the holding plates 16 a to 16 c, the end portion of the canopy member 18, the upper portion of the pallet 12, specifically, the top plate 22, By tightly winding so as to cover the upper part of the L-shaped girder 24 and the like, in other words, by stretch wrapping, it is possible to obtain an integrated packing body 32 that is tightened more effectively. The present invention is advantageously employed.

  Therefore, in the packaging body 32 having such a structure as shown in FIG. 6, a cardboard pallet 12 is used and a heavy wooden pallet is not used as in the conventional case. 12 can be effectively realized, and the weight of the entire packaging body 32 can be advantageously reduced, so that the manufacturing operation of the packaging body 32 and further such packaging body 32 can be performed. Thus, the physical burden on the workers involved in the transportation work can be advantageously reduced.

  Further, as shown in FIG. 2, the pallet 12 in the illustrated packaging body 32 has a rectangular shape and is fixed to the lower surface of the upper surface plate 22, and an L-shaped girder 24 as a leg portion or a rectangular shape. Since the girders 26 are disposed with a predetermined gap therebetween, the L-shaped girders 24 and the rectangular girders 26 are arranged on each side of the rectangle of the pallet 12 when the packing body 32 is conveyed by a forklift. Since the forklift fork is inserted into the gap and the packing body 32 can be lifted and transported, the transportability of the packing body 32 is also excellent.

  Further, the packaging body 32 obtained by stacking a plurality of LWCs 14 obtained as described above is stacked in a plurality of stages as shown in FIGS. 7 and 8, for transportation or transportation. Will be served. That is, in this case, the columns 20 in the upper and lower packing bodies 32, 32 are arranged in series in a form in which they are abutted with each other via the canopy member 18 of the lower packing body 32. Thereby, the load of the upper package 32 is transmitted to the four columns 20 of the lower package 32 via the canopy member 18 of the lower package 32, and the columns 20 are By coming into contact with the placement surface 30 of the lower package 32, the placement surface 30 is supported. Therefore, since the load of the upper packaging body 32 hardly acts on the lower packaging body 32 except for the support column 20, the pallet 12 of the lower packaging body 32 is simply lower. Since it is sufficient to support the load of the three LWCs 14 of the side packing body 32, it can sufficiently cope with the strength, and the problem such as deformation of the pallet 12 is not caused at all. .

  The exemplary embodiments of the present invention have been described in detail above. However, these are merely examples, and the present invention is not limited in any way by specific descriptions according to such embodiments. It should be understood that this is not to be construed as a manual.

For example, with respect to the canopy member, in the above-described embodiment, the cross-shaped canopy member 18 is formed by a combination using a single plate material. However, as shown in FIG. The canopy member 38 combined with the cross shape is also advantageously used. Such a canopy member 38 connects the long plate 38a, which is a combination of two upper and lower plates, the short plate 38b, which is a combination of two upper and lower plates, and the long plate 38a and the short plate 38b. It is comprised from the metal fitting 38c. Then, the lower long plate 38a ₁ and the lower short plate 38b ₁ are combined in a cross shape so that a cross shape having a length matching the outer peripheral surface (outer diameter) of the upper holding plate 16a is obtained. In addition, the upper long plate 38a ₂ and the upper short plate 38b ₂ are combined in a cross shape so that each end protrudes outward from the outer peripheral surface of the upper holding plate 16a. Yes. As a result, between the end of the upper long plate 38a _{2 and} the end of the lower long plate 38a ₁ , and the end of the upper short plate 38b _{2 and} the end of the lower short plate 38b ₁ . A stepped portion is formed between each portion, and the upper end portion of each column 20 is locked to the stepped portion. By doing so, the horizontal movement of the canopy member 38 is effectively prevented based on the locking of the upper end portion of each support column 20, and at the same time, the inward displacement of each support column 20 is also prevented. Generation | occurrence | production of problems, such as a collapse of a form, will be avoided advantageously.

  Each of the long plate 38a and the short plate 38b in the canopy member 38 is composed of two upper and lower plate members. Of course, each of the thick plate members is made of one plate. It is also possible to adopt a configuration in which a stepped structure is formed in which the end portion is cut out and the upper end portion of the support column 20 is locked as shown in FIG.

  Further, the canopy members 18 and 38 can be made of a rigid member such as a light metal material in addition to being made of wood. A shape such as a plate shape may be used, and a shape capable of receiving a load of another package (32) stacked on the plate and transmitting the load to the column 20 is appropriately adopted.

  In the present invention, the load of the packing body 32 stacked on the upper side is received and transmitted to the column 20 of the lower packing body 32 according to the shape of the canopy members 18, 38 according to the shape of the column 20. The number will be selected appropriately.

  Furthermore, even in the structure of the corrugated cardboard pallet 12, various structures having the top plate 22 and the leg portions supporting the top plate 22 can be used. As shown in FIG. In addition to the pallet 12 having a structure that can be inserted from four sides, various shapes of girders that can be attached to the lower surface of the upper surface plate 22 as the leg portions can be employed.

  In addition, although not listed one by one, the present invention can be implemented in a mode with various changes, modifications, improvements, and the like based on the knowledge of those skilled in the art. It goes without saying that any one of them falls within the scope of the present invention without departing from the spirit of the invention.
