Description

  TECHNICAL FIELD The present invention relates to a packaging material for a hollow cylindrical strip-shaped member bundle and a method for packaging a strip-shaped member bundle using the packaging material.

  Conventionally, in order to rehabilitate existing pipes such as aging sewer pipes, it has been carried out that a spiral pipe is wound around a belt-shaped member to form a spiral pipe, and the existing pipe is lined with the pipe-formed spiral pipe. Yes. The belt-shaped member used for this construction is transported to the construction site as a hollow cylindrical belt-shaped member bundle. Specifically, the band-shaped member bundle is formed by winding the band-shaped member in a hollow cylindrical shape using a production drum, and then preventing the band-shaped member from being unwound. It is manufactured by winding and binding a binding band through a cushioning material over the inner peripheral surface, the left and right side surfaces, and the outer peripheral surface of the hollow cylindrical belt-like member at intervals of degrees (see, for example, Patent Document 1).

  Such a band-shaped member bundle is packaged with a sheet-shaped packaging material in order to prevent damage or contamination of the band-shaped member, deterioration due to ultraviolet rays, etc. during storage in a factory or transportation to a construction site (for example, , See Patent Document 2).

  By the way, since the band-shaped member bundle is manufactured by winding the band-shaped member around the production drum, the inner diameter and the width thereof are defined by the production drum. On the other hand, the outer diameter of the band-shaped member bundle is changed depending on the length of the band-shaped member to be wound.

  In this case, the outer diameter rarely exceeds the reference outer diameter due to the maximum ground clearance when trucking the band member bundle, but depending on the type of the band member, the outer diameter is smaller than the reference outer diameter. In some cases, a band-shaped member bundle is manufactured.

  Here, the packaging material shown in Patent Document 2 is based on the premise that the inner and outer diameters and widths of the hollow cylindrical strip member to be packaged are constant, and the hollow cylindrical strip member having a smaller diameter than the reference outer diameter is used. When packaging, the following problems may occur. That is, the covering portion is applied to the outer peripheral surface of the hollow cylindrical belt-like member and folded on the left and right side surfaces, and the left and right coating sheets are folded and overlapped on the inner peripheral surface of the hollow cylindrical belt-shaped member, respectively. In addition, on the inner peripheral surface, the side edge of the upper cover sheet that has been overlapped is sealed by adhering an adhesive tape to the other cover sheet, so that the outer diameter of the hollow cylindrical strip member is reduced. The left and right side edge portions of the covering portion move to the inner peripheral surface, and the covering sheet is bumped or displaced, and the appearance is lowered. Moreover, on the inner peripheral surface of the band-shaped member bundle, sticking over the entire circumference so as to seal the overlapped portion of the covering sheet that has been bumped or displaced with an adhesive tape is a restricted working space and unnatural. Combined with working posture, it is not easy. For this reason, when the strip-shaped member bundle packaged with the packaging material, that is, when the package is stored outdoors or transported, it is rained from an incompletely sealed portion by the adhesive tape of the overlapping portion of the left and right covering sheets. Intrusion may occur and rainwater may accumulate inside the package, which may cause the strip member to become soiled or the packaging material to be peeled off during transportation, causing rainwater to leach into the carrier. Can do.

  The present invention has been made in view of such problems, and even when the outer diameter of the band-shaped member bundle is smaller than the reference value, the overlapping portion can be reliably sealed and efficiently packaged. The present invention provides a packaging material for a band-like member bundle that can be produced and a packaging method therefor.

  The packaging material for the band-shaped member bundle of the present invention is a packaging material for wrapping a hollow cylindrical band-shaped member bundle, and has a length longer than the circumferential length of the inner peripheral surface of the band-shaped member bundle. A rectangular inner peripheral covering material having a width corresponding to the width, and the inner side one side edge is connected to the left and right side edges of the inner peripheral covering material, respectively, and the peripheral length of the outer peripheral surface of the band-shaped member bundle Each outer periphery is composed of a rectangular left and right outer covering material having a long length and a width that secures an overlap margin in the width direction of the outer peripheral surface when folded back to the outer peripheral surface through the left and right side surfaces of the band-shaped member bundle. The inner side edge of the side covering material is reduced to a length corresponding to the length of the inner periphery covering material by a plurality of pleats.

  According to the present invention, one end edge in the longitudinal direction of the inner peripheral covering material of the packaging material is attached to the inner peripheral surface of the selected cushioning material of the band-shaped member bundle, and the inner end surface is used as a reference. While the peripheral covering material is wound around the inner peripheral surface of the band-shaped member bundle, the left and right outer peripheral side covering materials are folded back along the left and right side surfaces of the band-shaped member bundle with respect to the inner peripheral covering material, It is wound in the circumferential direction of the left and right side surfaces and the outer peripheral surface while being folded back along. At this time, by arranging the left and right outer peripheral side covering materials while extending the pleats on the outer peripheral surface of the band-shaped member bundle, it is possible to wind them without causing looseness or slack.

  Therefore, even if it is a band-shaped member bundle whose outer diameter is smaller than the reference, the overlapping margin in the width direction and the circumferential direction becomes large, but it is wound around the outer peripheral surface without causing bumps or slack by extending the pleats. It is possible to rotate, and the circumferential overlapping portion and the width overlapping portion can be reliably adhered in a sealed state. Moreover, it can be packaged in a standing position mainly on the outside of the band-shaped member bundle, and can work efficiently.

  As a result, not only the standard band-shaped member bundle but also the smaller diameter than that, the overlapping portion can be reliably sealed and efficiently packaged.

  In the method of wrapping a band-shaped member bundle according to the present invention, the left and right side surfaces, the inner peripheral surface, and the outer peripheral surface of the hollow cylindrical band-shaped member are bound by a plurality of binding bands via a cushioning material at intervals in the circumferential direction. A packaging method for packaging a band-shaped member bundle, wherein one end edge in the longitudinal direction of the inner peripheral coating material of the packaging material according to claim 1 is attached to an inner circumferential surface of a selected buffer material of the band-shaped member bundle. In addition, the longitudinal one end edges of the left and right outer peripheral side covering materials that are continuous with the one longitudinal end edge of the inner peripheral covering material are folded back to the outer peripheral surface through the left and right side surfaces of the band-shaped member bundle, respectively, Attaching the mating part, and then winding it around the inner peripheral surface of the band-shaped member bundle with the one end edge in the longitudinal direction to which the inner peripheral covering material is attached as the starting end, The outer side covering material is attached to the left and right side surfaces of the band-shaped member bundle. The outer peripheral surface of the upper outer peripheral side covering material is used as the lower outer peripheral side covering material. Adhering over the entire circumference and sealing those overlapping parts, then the other end edge of the inner peripheral covering material and the other end edge of the outer peripheral covering material on the left and right inner peripheral covering material below And it sticks to the outer peripheral side covering material on either side, and those overlap parts are sealed.

  According to the present invention, one end edge in the longitudinal direction of the inner peripheral covering material of the packaging material according to claim 1 is attached to the inner peripheral surface of the selected cushioning material of the band-shaped member bundle so as to match the width, The one end edge in the longitudinal direction of the left and right outer periphery side covering materials continuous to the one end edge in the longitudinal direction of the inner periphery covering material is folded back to the outer peripheral surface via the left and right side surfaces of the band-shaped member bundle, respectively, Adhere. And while winding around the inner peripheral surface of the band-shaped member bundle body with the one end edge in the longitudinal direction to which the inner peripheral covering material has been attached as a starting end, the outer peripheral covering material on the left and right outer sides are respectively strip-shaped. It is folded over and overlapped with the outer peripheral surface through the left and right side surfaces of the member bundle, and wound around the one end edge of the start end side. Further, the other peripheral edge of the upper outer peripheral side covering material of the left and right outer peripheral side covering materials is adhered to the lower outer peripheral side covering material over the entire periphery, and the overlapping portion is sealed, and then the inner peripheral covering material is sealed. Are attached to the lower inner peripheral covering material and the left and right outer peripheral covering materials, and the overlapping portions thereof are sealed.

  Here, when the left and right outer peripheral side covering materials are disposed on the outer peripheral surface through the left and right side surfaces of the band-shaped member bundle, the overlap allowance increases even if the outer diameter of the band-shaped member bundle is smaller than the reference. However, as in the case of the standard outer diameter, it can be wound without causing bumps or slack by stretching the pleats. Therefore, the overlapping portion in the circumferential direction of the inner peripheral covering material and the overlapping portions in the circumferential direction and the width direction of the left and right outer covering materials can be reliably adhered in a sealed state. Moreover, it can be packaged in a standing position mainly on the outside of the band-shaped member bundle, and can work efficiently.

  As a result, not only the standard band-shaped member bundle but also the smaller diameter than that, the overlapping portion can be reliably sealed and efficiently packaged.

  In this invention, it is preferable to stick the longitudinal direction one end edge of the inner peripheral coating | covering material of a packaging material to the buffer material nearest the winding direction downstream of the winding end edge part of the strip | belt-shaped member in a strip | belt-shaped member binding body. Thereby, the terminal end side other end edge can be arrange | positioned above the one end edge of the inner end covering material over the start end side. Similarly, it is possible to dispose the other end edge on the end side beyond the one end edge on the start end side of the left and right outer peripheral side covering materials. In this case, the length in the longitudinal direction of the inner peripheral covering material and the length in the longitudinal direction of the outer peripheral covering material are appropriately set corresponding to the inner and outer diameters (peripheral lengths) of the band-shaped member bundle, and from the top to the bottom. It is possible to arrange the terminal end other end edge of the inner peripheral covering material and the terminal end other end edge of the outer peripheral covering material in a state where the opening by the overlapping portion faces downward by winding toward the side. This makes it possible to further suppress the intrusion of rainwater and the like.

  According to the present invention, even when the outer diameter of the band-shaped member bundle is smaller than the reference value, the overlapping portion can be reliably sealed and efficiently packaged.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an embodiment of a packaging material 1 for a hollow cylindrical strip-shaped member bundle 10 of the present invention.

  First, prior to describing the packaging material 1, the band-shaped member bundle 10 to be packaged will be described.

  The band-shaped member bundle 10 is formed by winding a long band-shaped member 100 around a production drum (not shown) to form a hollow cylinder, and preventing the band-shaped member 100 from being unwound. It is manufactured by winding and binding a binding band 103 via a cushioning material 102 such as cardboard at intervals of 90 degrees in the circumferential direction across the surface, the left and right side surfaces, and the outer peripheral surface. This band-shaped member bundle 10 is set with an outer diameter of 2000 mm, an inner diameter of 1200 mm, and a width of 1100 mm as a standard size. In this case, the peripheral length of the outer peripheral surface of the band-shaped member bundle 10 is 6280 mm, and the peripheral length of the inner peripheral surface is 3768 mm.

  In addition, the connection string 110 for connecting with the construction drum 7 mentioned later is connected to the winding end part of the strip | belt-shaped member 100. As shown in FIG.

  The packaging material 1 for packaging the band-shaped member bundle 10 includes an inner peripheral covering material 2 and left and right outer peripheral covering materials in which one inner side edge is sewn to each of the left and right side edges of the inner peripheral covering material 2. 3 and 3, and is formed of a light-shielding material, for example, a polyethylene terephthalate film or polyethylene film (thickness 0.15 mm) on which aluminum is deposited.

  The inner periphery covering material 2 is formed in a rectangular shape having a length of 4600 mm and a width of 1220 mm, and the left and right side edges are folded back inward by the sewing allowance so as to have a width corresponding to the width of the band-shaped member bundle 10. The left and right side edges of the outer peripheral side covering material 3 on the right and left sides are sewed against one side edge of the inner side that is folded back by the sewing allowance.

  Each outer peripheral side covering material 3 is formed in a rectangular shape having a length of 6600 mm and a width of 1000 mm, and a plurality of pleats 31 are sewn on one inner edge of the inner side, and the length in the longitudinal direction is the length of the inner peripheral covering material 2. This is reduced to 4600 mm. Then, as described above, the inner side one side edge of the outer peripheral side covering material 3 is folded back by the sewing allowance, and is sewed by being brought into contact with the left and right side edges that are folded back by the sewing allowance of the inner peripheral covering material 2. . That is, as shown in FIG. 1, each outer covering material 3 is formed with a plurality of pleats 31 extending from one inner side edge to the other outer side edge. In this case, only the inner side one side edge of each pleat 31 is sewn, and by extending the pleats 31 other than the inner side one side edge, the outer side other side edge of each outer peripheral side covering material 3 is The belt-shaped member bundle 10 is deformed into an annular shape having a length exceeding the circumferential length of the outer circumferential surface.

  In this embodiment, the chasing pleat is formed as the pleat 31 of the outer peripheral side covering material 3, but it is not limited to the chasing pleat as long as it can be shortened to the length of the inner peripheral covering material 2, and may be a box pleat. . Further, the pleats 31 may be formed regularly at set intervals or irregularly. Further, the pleats 31 may be formed symmetrically in the left and right outer peripheral side covering materials 3 with respect to the inner peripheral covering material 2 or may be formed in left and right asymmetrical shapes.

  Further, each outer covering material 3 is formed with a plurality of drain holes 3a with C-shaped cuts at a set interval from one edge in the longitudinal direction. Specifically, when a horizontal plane passing through the center of the band-shaped member bundle 10 is used as a reference, and the one end edge in the longitudinal direction of the outer peripheral side covering material 3 is aligned with this reference and winding starts, it corresponds to the bottom of the band-shaped member bundle 10. And a plurality of drain holes 3a are arranged.

  Next, the process of packaging the band-shaped member bundle 10 with the packaging material 1 formed in this way will be described.

  First, the band-shaped member bundle 10 is lifted using a forklift truck and separated from the ground. At this time, with reference to the winding end end of the belt-like member 100, the cushioning material 102s positioned immediately downstream in the winding direction is adjusted so as to be substantially located on a horizontal plane passing through the center of the belt-like member bundle 10.

  If the band-shaped member bundle 10 is supported, after the double-sided tape is attached to the inner circumferential surface width direction of the cushioning material 102s located on the horizontal plane, the packaging material 1 is inserted into the hollow part of the band-shaped member bundle 10; One end edge in the longitudinal direction of the inner peripheral covering material 2 is attached to a double-sided tape in accordance with the width of the band-shaped member bundle 10 (see FIG. 2). Furthermore, the longitudinal direction one edge of the left and right outer peripheral side covering materials 3 continuing to the longitudinal direction one end edge of the inner peripheral covering material 2 in the packaging material 1 is folded back to the left and right side surfaces of the band-shaped member bundle 10, respectively. After overlapping and overlapping on the outer peripheral surface, the other outer edge of the longitudinal direction one end edge of the upper outer peripheral side covering material 3 and the lower outer peripheral side covering material among the overlapped left and right outer peripheral side covering materials 3 and 3 Adhesive tape 5 is attached to 3 and set as a packaging start position (see FIG. 3).

  Next, the inner peripheral covering material 2 is wound along the inner peripheral surface of the band-shaped member bundle 10 with the one end edge in the longitudinal direction to which the inner peripheral covering material 2 of the packaging material 1 is attached as a starting end. In addition, the left and right outer peripheral side covering materials 3 and 3 are folded back to the outer peripheral surface through the left and right side surfaces of the band-shaped member bundle 10 with respect to the left and right side edges of the inner peripheral covering material 2, respectively, One end edge in the direction is used as a starting end, and the winding is performed in the circumferential direction while maintaining the upper and lower overlapping. Under the present circumstances, it winds in the circumferential direction, extending each pleat 31 of the part arrange | positioned in the outer peripheral surface of the strip | belt-shaped member binding body 10 of the outer peripheral side covering material 3 in order. Thereby, the outer peripheral side coating | covering material 3 deform | transforms cyclically | annularly so that the outer peripheral surface of the strip | belt-shaped member binding body 10 may be followed, and it arrange | positions without generating looseness and a slack on the outer peripheral surface (refer FIG. 4).

  In addition, the connecting string 110 connected to the winding end end portion of the belt-like member 100 is drawn out so as to be positioned on the outer surface side of the upper outer peripheral side covering material 3.

  Thus, by winding the inner peripheral covering material 2 of the packaging material 1 along the inner peripheral surface of the band-shaped member bundle 10, the other end of the end side is the inner periphery of the buffer material 102 s of the band-shaped member bundle 10. It arrange | positions beyond the one end edge of the starting end side stuck on the surface. Further, by winding the left and right outer peripheral side covering materials 3 and 3 of the packaging material 1 in the circumferential direction while folding them back to the outer peripheral surface through the left and right side surfaces of the band-shaped member bundle 10, respectively, It is arranged beyond the one end edge of the wearing start side (see FIG. 6). Specifically, one end edge of the inner peripheral covering material 2 in the packaging material 1 is disposed 832 mm away from the first end edge in the circumferential direction on the inner peripheral surface of the band-shaped member bundle 10, The one end edge of the covering material 3, 3 is arranged on the outer peripheral surface of the band-shaped member bundle 10 at a distance of 320 mm from the one end edge of the start end side in the circumferential direction. Further, the left and right outer peripheral side covering materials 3 and 3 are overlapped on the outer peripheral surface of the band-shaped member bundle 10 while securing a stacking allowance of 100 mm in the width direction.

  If the inner peripheral surface, the left and right side surfaces, and the outer peripheral surface of the band-shaped member bundle 10 are covered with the packaging material 1, the left and right outer-side covering materials 3 and 3 overlapped on the outer peripheral surface of the band-shaped member bundle 10. The adhesive tape 5 is pasted over the entire circumference so as to go from the top side to the bottom side of the band-shaped member bundle 10 on the other side edge portion of the upper outer circumference side covering material 3 and the outer circumference side covering material 3 arranged therebelow. Wear and seal their overlap. Further, the terminal end other end edge of the inner peripheral covering material 2 of the packaging material 1 and the terminal end other end edge of the left and right outer peripheral covering materials 3, 3 and the inner peripheral covering material 2 and the left and right disposed below them. The adhesive tape 5 is attached to the outer peripheral side covering materials 3, 3, and the overlapping portions over the inner peripheral surface, the left and right side surfaces, and the outer peripheral surface of the band-shaped member bundle 10 are sealed.

  The connecting string 110 connected to the winding end end of the belt-like member 100 is pulled out beyond the terminal end side edge of the outer peripheral side covering material 3. Further, a drain hole 3 a formed in the outer peripheral side covering material 3 is arranged corresponding to the bottom of the band-shaped member bundle 10.

  Next, after placing a pallet (not shown) below the band-shaped member bundle 10 packaged by the packaging material 1, that is, the package 10A (see FIG. 5), the fork is lowered and the package 10A is placed on the pallet. Then, the adhesive tape is wound around the inner peripheral surface of the pallet and the package 10A to fix the package 10A to the pallet. The package 10A thus formed is stored in a factory or the like together with the pallet, or is transported to a construction site.

  As described above, the band-shaped member bundle 10 is packaged by the packaging material 1, and the overlapping portions in the width direction of the outer peripheral side covering materials 3, 3 on the outer circumferential surface of the band-shaped member bundle 10 of the packaging material 1, When the overlapping portions in the circumferential direction of the inner peripheral covering material 2 and the left and right outer peripheral covering materials 3 and 3 on the inner peripheral surface, the left and right side surfaces, and the outer peripheral surface of the band-shaped member bundle 10 are respectively sealed with the adhesive tape 5. In addition to preventing deterioration of the belt-shaped member 100 due to ultraviolet rays, it is possible to prevent rainwater or the like from entering and prevent the belt-shaped member 100 from being damaged due to the intrusion of rainwater.

  Moreover, the left and right outer covering materials 3 and 3 are loosened or loosened by covering the left and right side surfaces and the outer peripheral surface of the band-shaped member bundle 10 in the circumferential direction and the width direction while extending the pleats 31, respectively. Can be disposed on the outer peripheral surface of the band-shaped member bundle 10 without causing wrinkles or unevenness due to the above, and the work space is expanded and the standing posture is mainly compared to the case of working on the inner peripheral side. Can work with. Therefore, when the overlapping portions in the circumferential direction and the width direction of the left and right outer covering materials 3 and 3 are stuck with the adhesive tape 5, the overlapping portions can be reliably sealed and work can be performed efficiently.

  Furthermore, the inner peripheral covering material 2 of the packaging material 1 has a length longer than the peripheral length of the inner peripheral surface of the band-shaped member bundle 10, and the left and right outer peripheral covering materials 3 and 3 are band-shaped member binding. Since it has a length longer than the peripheral length of the outer peripheral surface of the body 10, the one end edge in the longitudinal direction of the packaging material 1 is wound downward as a starting end in accordance with the horizontal line including the center of the band-shaped member bundle 10 and wrapped. When this is done, the other end edge of the wrapping material 1 is positioned on the lower half side of the band-shaped member bundle 10 beyond the one end edge of the start end side, that is, the opening of the overlapping portion faces downward. By setting the length in the longitudinal direction as described above, even if there is a problem in the sealing performance by the adhesive tape 5, the intrusion of rainwater or the like can be suppressed as much as possible.

  By the way, in embodiment mentioned above, although the case where the strip-shaped member binding body 10 of standard size was packaged with the packaging material 1 was illustrated, the same packaging material is also used when packaging the strip-shaped member binding body 10 smaller in diameter than the standard size. 1 may be used for similar packaging. That is, even the band-shaped member bundle 10 having a smaller diameter than the standard size has the same inner diameter and width, and therefore can be covered with the inner peripheral covering material 2 without any change. Also, the left and right outer covering materials 3 and 3 in which the inner side one side edge is connected to the left and right side edges of the inner covering member 2 are the left and right side portions of the band-shaped member bundle 10 having a small diameter. As a result, the position folded back to the outer peripheral surface is advanced, the overlap in the width direction is increased, and the overlap in the circumferential direction is increased. However, by extending the pleats 31, There is no change in being able to be wound and coated without causing slack, and the same operation can be performed.

  On the other hand, the package 10A is transported to the construction site for each pallet and mounted on the construction drum 7 at the construction site. Specifically, after fixing the packaging body 10A and the pallet and removing the pallet, the construction drum 7 is disposed facing the packaging body 10A, and is rolled toward the packaging body 10A. To house. Next, a plurality of connecting rods 72 are connected in order between the left and right side frames 71, 71 in accordance with the outer peripheral surface of the packaging body 10A to surround the periphery, and then the connecting string extending from the other end edge of the packaging material 1 If 110 is fixed to one side frame 71, the drawing of the band-shaped member 100 can be started. That is, after cutting the sewing portion between the inner peripheral covering material 2 and the left and right outer peripheral covering materials 3, 3 in the packaging material 1 and taking out the inner peripheral covering material 2, the binding band 103 and the buffer material 102 are cut. The winding start end of the belt-like member 100 can be pulled out from the inner peripheral surface of the hollow cylindrical belt-like member 101. At this time, by connecting the connecting string 110 to the side frame 71 of the construction drum 7, the restoring force at the time of elastic deformation acts on the band-shaped member 100 due to the cutting of the binding band 103 to move in the circumferential direction and increase the diameter. Can be suppressed together with the connecting rod 72.

  In the above-described embodiment, the widths of the left and right outer peripheral side covering materials 3 and 3 are smaller than the sum of the difference between the inner and outer diameters of the band-shaped member bundle 10 and its width, and the inner and outer diameters of the band-shaped member bundle 10. Is set to 1000 mm, which is larger than the sum of the difference between them and 1/2 of the width, but the left and right outer covering materials 3 and 3 are folded back to the outer peripheral surface through the left and right outer peripheral surfaces of the band-like member bundle 10 respectively. In this case, it is only necessary that the left and right outer peripheral side covering materials 3 and 3 can be arranged with a certain overlap margin in the width direction, and the widths of the left and right outer peripheral side covering materials 3 and 3 are not necessarily the same.
