Description

The present invention relates to a technology for packaging a tubular body made of a fiber material that is easily crushed, such as a heat insulating barrel made of inorganic fibers.

無機 Some heat-retaining cylinders made of inorganic fibers such as rock wool and glass wool are easily crushed when compressed, and it is necessary to prevent damage such as crushing during transportation. In particular, since the heat retaining cylinder is attached to the pipe with the ends thereof abutting each other, damage to the ends must be avoided. For this reason, as the current packing form of the heat retaining cylinder, cardboard box packing is used. However, packaging in a cardboard box requires a cardboard box that completely accommodates the heat retaining tube, which increases the packaging cost, and unpacked cardboard boxes become garbage at the construction site, which generates a large amount of garbage. There was a problem.

Therefore, a packaging form that replaces cardboard boxes is desired. Although it is not a packaging of a heat retaining cylinder, as a packaging technique of a rod-shaped article, Japanese Patent Application Laid-Open No. 52-54591 discloses a technique in which a plurality of rod-shaped articles are stacked on a U-shaped guide and aligned. A method of assembling a cap from cardboard, covering both ends of the article with the cap, and wrapping it with a shrinkable film from above is described. Japanese Patent Publication No. 62-4294 discloses a method of connecting a pipe or rod to a core. Since a method of arranging with a letter-shaped guide and wrapping both ends or the whole with a shrinkable film or a stretch film is described, it is conceivable to apply these to the packaging of a heat insulating cylinder.

However, the packaging method described in Japanese Patent Application Laid-Open No. 52-54591 has a problem in that productivity is not good because the caps at both ends are assembled while being stacked on the U-shaped guide. In addition, in the packaging method described in Japanese Patent Publication No. 62-4294, since there is no protective material at both ends of the formed package, there is a risk of breakage when handling the package upside down. there were.

In addition, since both ends of the heat insulation tube are protected by protective materials, even if the package is placed vertically, the end of the heat insulation tube that is easily crushed may be damaged. The effect that there is no is obtained.

The object of the packaging in the present invention is arbitrary as long as it is a tubular body made of a fiber material that is easily crushed when compressed, and the shape is also arbitrary such as a cylindrical shape or a rectangular tubular shape. In this specification, the cylindrical body is not limited to a hollow structure, but also includes a solid structure. As a typical example of the cylindrical body, a heat insulating cylinder made of an inorganic fiber such as rock wool or glass wool can be given. Hereinafter, an embodiment of the present invention will be described using a heat retaining cylinder as an example.

FIG. 1 shows a typical packaging form of the present invention. The package indicated by reference numeral 1 is a package in which four heat retaining cylinders 2 made of inorganic fiber are packaged, and the four heat retaining cylinders 2 are arranged in such a manner that their body portions are in contact with each other. A plate-like protective material 3 is applied to both end surfaces of the film, and a film-like soft packaging material 4 is wound around the four heat retaining cylinders 2 and the protective material 3 to be integrated as a whole. The protective material 3 used here is for protecting the end faces of the heat retaining cylinder 2 and has a size capable of covering almost the entire end faces of the four heat retaining cylinders 2 and has the necessary strength for protection. Things are used. Further, the protective material 3 is preferably lightweight and capable of easily performing disposal such as disposal, and specifically, cardboard made of paper is suitable. The planar shape of the protective material 3 is a quadrangle in FIG. 1C, but is not limited to this, and the corner of the quadrangle is formed into an arc shape in accordance with the shape of the heat retaining cylinder 2, and the whole is circular, polygonal, etc. It is optional. Further, the protective material 3 is not limited to a flat plate-like material, but may be provided on the periphery of the flat portion 3a pressed against the end surface of the heat retaining cylinder 2 like the protective material 3A used for the package 1A shown in FIG. May be provided with an upright wall portion 3b for protecting the outer peripheral surface of the end portion. The upright wall 3b is not limited to being provided on the entire circumference of the flat portion 3a, but may be provided mainly in a region in contact with the heat retaining cylinder 2. The protective material 3A of this embodiment can be easily formed by bending a plate material such as a cardboard used for the protective material 3A at an appropriate position.

In FIG. 1, as the soft wrapping material 4 for wrapping the heat insulating tube 2 together with the protective material 3, various materials can be used as long as the heat insulating tube 2 and the protective material 3 can be wrapped integrally. Examples include a film, a laminated film, and paper. Further, in the drawings, the entire length of the heat retaining cylinder 2 is wrapped by wrapping the soft wrapping material 4 having a narrow width in a helical manner and partially overlapping, but the present invention is not limited to this mode. May also be wrapped using a wide width soft wrapping material. At both ends of the heat retaining cylinder 2, the soft packaging material 4 is wound so that a part of the width direction of the soft packaging material 4 extends outside the protective material 3 (to the side opposite to the heat retaining cylinder 2). A part 4a in the width direction of 4 is wound around the outer surface of the protective material 3, so that the protective material 3 can be kept fixed to the heat retaining cylinder 2. If necessary, a part 4a of the soft packaging material may be attached to the protective material 3 using an appropriate means such as an adhesive tape or an adhesive. When a resin film is used as the soft packaging material 4, it is preferable to use a stretch film or a heat-shrinkable film. Since the stretch film usually has large elongation and self-adhesiveness, it can be wrapped tightly according to the shape of the heat insulating cylinder 2 and the protective material 3 only by winding the stretch film around the heat insulating cylinder 2 and the protective material 3 with an appropriate tension. In the obtained package, the heat insulating cylinder 2 and the protective material 3 are tightly packed with a stretch film, so that it is possible to prevent the collapse of the load during transportation for a long period of time. When a heat-shrinkable film is used, the heat-insulating cylinder 2 and the protective material 3 can be tightly packed by heat-shrinking after packaging, and the collapse of the load during transportation can be prevented for a long period of time.

In the package 1 having the above configuration, the heat insulating tube 2 is packaged with only the protective material 3 and the soft packaging material 4 arranged at both ends, so that it is packed with a much smaller amount of packaging material as compared with the case where it is stored in a cardboard box. And packaging costs can be reduced. In transporting or storing, even if the package 1 is placed vertically, the end of the heat insulating tube 2 that is easily crushed is protected by the protective material 3, so that the end is not damaged. Furthermore, as a result of reducing the amount of packaging materials, unpacking work at the construction site is easy, and the amount of dust generated can be reduced.

Although the example in which the four heat insulation tubes 2 are wrapped has been described above, the number and arrangement of the heat insulation tubes wrapped in one package can be variously changed, and the size of the protective material arranged on the end face of the heat insulation tube 2 can be changed. The sheath shape can also be appropriately changed according to the number and arrangement of the heat retaining cylinders. Some examples are shown in FIGS. In addition, in the figure, 3B, 3C, 3D, 3E, 3F, and 3G each show a protective material.

In addition, the arrangement of the heat retaining cylinders 2 is not limited to the case where the trunks of the individual heat retaining cylinders 2 are simply arranged in contact with each other, but as shown in FIG. And a plurality of the combined heat retaining cylinders 2 may be arranged in contact with the body. In the figure, 3H indicates a protective material.

Next, a packaging method and a packaging device for forming the package 1 having the above configuration will be described. FIG. 5 is a schematic side view of the packaging apparatus, 10 is a packaging apparatus, 11 is a base, 12 is a main body tower provided on the base 11, and 13 is a base that can rotate about a substantially vertical axis. Reference numeral 11 denotes a rotary table held on the rotary table, and reference numeral 14 denotes a work alignment receiving table provided on the rotary table 13. The work alignment receiving table 14 includes a support table 16 fixed to the rotary table 13 and a work alignment member 17 held by the support table 16. As shown in FIG. 6, the work aligning member 17 includes a base plate 17a having a receiving surface for supporting the protection member 3, and a plurality of support plates 17b provided vertically at appropriate positions around the base plate 17a. I have. Here, the base plate 17a has a shape capable of supporting the protective material 3 placed thereon in such a manner that the peripheral portion of the lower surface is partially exposed. This is to allow a part of the soft wrapping material to be wrapped around the lower surface of the protection material 3 when the soft wrapping material 4 is wrapped around the protection material 3. The plurality of support plates 17b restrain the outside of the lower part of the plurality of heat insulating tubes 2 arranged vertically on the protective material 3 placed on the base plate 17a, and support the heat insulating tubes so that they do not slip or fall. And arranged at a position where it can come into contact with a part of the outer periphery of each heat retaining cylinder 2. The support plate 17b can be easily deformed outward when the heat retaining cylinder 2 is inserted into the inside thereof, and can be supported so that the heat retaining cylinder 2 does not fall down after the heat retaining cylinder 2 is inserted. As described above, after the soft wrapping material is wound around the heat insulating cylinder 2 and the support plate 17b supporting the same, the thin and elastic material can be easily pulled out from between the soft wrapping material and the heat insulating cylinder. , For example, a leaf spring is preferred. Examples of the material of the support plate 17b include metals such as stainless steel and plastic. The thickness of the support plate 17b is preferably selected to be about 0.3 to 2 mm, and more preferably about 0.5 to 1 mm. The protruding height of the support plate 17b from the base plate 17a is determined so as to be able to support the heat insulating cylinder 2 inserted inside the support plate 17b so as not to fall down, and varies depending on the size of the heat insulating cylinder. In many cases, the thickness is preferably about 200 to 500 mm. In addition, when the flexible packaging material 4 is wound around the lower end region of the heat insulating cylinder 2 and around the support plate 17b, the lower end of the support plate 17b extends below the flexible packaging material 4. Thus, the support plate 17b is attached so as to extend below the base plate 17a, whereby the support plate 17b can be pulled out without any trouble. The protruding length downward from the base plate 17a is preferably about 100 to 200 mm.

In FIG. 5, the support base 16 and the work alignment member 17 constituting the work alignment receiving base 14 may be formed as an integral structure. However, in the preferred embodiment shown in FIG. It is possible. This makes it possible to perform packaging in a different packaging form by using a work alignment member suitable for the packaging form. For example, as shown in FIG. 7, when four sets of the combination of the two heat retaining cylinders 2 are packaged together, the work alignment member 17A in which the support plate 17b is arranged at a position where each of the heat retaining cylinders 2 contacts is used. It may be used.

In FIG. 5, reference numeral 21 denotes an elevating table held by the main body tower 12 so as to elevate and lower above the rotary table 13. Reference numeral 22 denotes a rotatable table that enables the elevating table 21 to rotate about the same axis as the rotation axis of the rotary table 13. It is a held work pushing table, and has a pushing surface 22a for pushing the protective material 3 placed on the heat retaining cylinder 2. The pressing surface 22a is formed to have a smaller area than the protective material 3, and exposes the outer peripheral portion of the upper surface of the protective material 3 in a state where the protective material 3 is pressed. This is to allow a part of the soft wrapping material to be wrapped around the upper surface of the protection material 3 when the soft wrapping material 4 is wrapped around the protection material 3. Reference numeral 25 denotes a soft-packing material feeding device that holds a soft-packing material 4 to be wound around the plurality of heat retaining cylinders 2, for example, a soft-packing material roll for feeding a stretch film, and is held by the main body tower 12 so as to be able to move up and down. The soft packaging material feeding device 25 is provided with a tension applying means, for example, a brake, so that an appropriate tension can be applied to the soft packaging material 4 to be fed. Although not shown, a driving device for rotating the rotary table 13, a driving device for raising and lowering the elevating table 21, and a driving device for raising and lowering the flexible packaging material feeding device 25 are also provided.

Next, a packaging method using the packaging device 10 will be described. In FIG. 1, the protective member 3 is placed on a work aligning member 17 on a rotary table 13, and the heat retaining cylinders 2 are erected thereon in a desired arrangement. At this time, the upright support plate 17b of the work aligning member 17 supports the heat retaining cylinder 2 inserted therein, so that the heat retaining cylinder 2 does not slip or fall, and the heat retaining cylinders 2 can be easily set up one after another. You can go side by side. After arranging a predetermined number of heat insulating cylinders 2, the protective material 3 is placed on the upper end thereof, the elevating table 21 is lowered, and the protective material 3 is pressed against the heat insulating cylinder 2 by the work pushing table 22. As a result, the plurality of heat retaining cylinders 2 and the protective materials 3 at the upper and lower ends thereof are sandwiched and held by the work alignment member 17 and the work pushing table 22. In this state, the soft wrapping material 4 such as a stretch film set on the soft wrapping material feeding device 25 is pulled out, and the front end of the soft wrapping material 4 is supported on the lower end region of the heat retaining cylinder 2 by the work alignment member 17. The soft wrapping material is wound out from the outside of the plate 17b so that a part of the width of the soft wrapping material is further lower than the protective material 3 located at the lower end of the heat retaining cylinder 2, and the rotating table 13 is rotated to feed out the soft wrapping material. The soft wrapping material 4 from the device 25 is wound around the heat retaining cylinder 2 and the soft wrapping material feeding device 25 is raised. At this time, a predetermined tension is applied to the soft packaging material 4 to be drawn out by the soft packaging material feeding device 25. Therefore, the soft packaging material 4 spirally surrounds the heat retaining cylinder 2 with a predetermined tension. And are wound in a partially overlapping state. Further, at the beginning of winding, the soft wrapping material portion wound below the protection material 3 is wrapped around the lower surface of the protection material 3 by the tension acting thereon, and fixes the protection material 3 to the heat retaining cylinder 2. When the soft wrapping material 4 is wound up to the upper end region of the heat insulating cylinder 2 and is wrapped until a portion of the soft wrapping material in the width direction is higher than the protection material 3 at the upper end, the soft wrapping material wound above the protection material 3 is obtained. The portion of the packaging material is wrapped around the upper surface of the protection material 3 by its own tension. Thereafter, the rotation of the turntable 13 is stopped, the soft wrapping material 4 is cut, and its end is pressed against the surface of the soft wrapping material or the protection material 3 which has been wound first, and fixed. At this time, when a stretch film is used as the soft wrapping material 4, the stretch film can be adhered by self-adhesion, so that it is not necessary to use an adhesive tape or an adhesive. The set can be easily cleaned. If the soft wrapping material 4 does not have self-adhesiveness, the end of the soft wrapping material 4 may be cleaned using an adhesive tape or an adhesive. Thereafter, the work pushing table 22 is retracted upward, the formed package is lifted upward, and the support plate 17b of the work alignment member 17 is pulled out from between the heat insulating cylinder 2 and the soft packaging material 4 wound therearound. The soft wrapping material extending below the protective material 3 is pressed and adhered to the lower surface of the protective material 3. By the above operation, the package 1 of the form shown in FIG. 1 is created.

When a heat-shrinkable film is used as a soft wrapping material for packaging the heat retaining cylinder 2, the plurality of heat retaining cylinders 2 held and held by the work alignment member 17 and the work pushing table 22 in the same manner as described above. A step of winding the heat-shrinkable film around the support plate 17b to form a package around the support plate 17b, and then heating and shrinking the heat-shrinkable film may be provided. In the case of packaging using a heat-shrinkable film, the heat-shrinkable film may be wound around the plurality of heat-retaining cylinders 2 without excessively increasing the tension or without applying the tension. There is no problem because it can be tightened. For this reason, the tension adjustment at the time of winding is almost unnecessary, and the winding operation is facilitated. The heating and shrinking steps of the heat-shrinkable film wound around the plurality of heat-insulating cylinders 2 may be performed after the plurality of heat-insulating cylinders 2 around which the heat-shrinkable films are wound are removed from the work alignment member 17, but will be described below. It is preferable to perform the treatment in two stages. That is, after loosely wrapping the plurality of heat insulating cylinders 2 with the heat shrinkable film, removing them from the work aligning member 17 and releasing the restraint by the support plate 17b, the alignment of the plurality of heat insulating cylinders 2 is disturbed. In some cases, even if the heat-shrinkable film is heat-shrinked, a good packing appearance may not be obtained. To avoid this, after winding the heat-shrinkable film around the plurality of heat-insulating cylinders 2, the plurality of heat-insulating cylinders 2 In a state where the heat-shrinkable film above the support plate 17b is restrained by the support plate 17b, the heat-shrinkable film is heated and shrunk to restrain the plurality of heat insulation tubes 2 in a tightened state. 2 and the heat-shrinkable film wrapping it are removed from the work alignment member 17 (the support plate 17b is pulled out from between the heat-retaining cylinder 2 and the heat-shrinkable film wound therearound), and thereafter, the heat-shrinkable film is not shrunk. Heating the heat-shrinkable film of the band, it is preferable to deflate. By dividing the heat-shrinkable film into two stages and heat-shrinking in this manner, the heat-shrinkable film can be satisfactorily heat-shrinked to the lower end region of the heat-insulating cylinder 2 without disturbing the aligned heat-insulating cylinders 2. It is possible to form a package with a proper packing.

As described above, the packaging method using the packaging apparatus 10 simply involves placing the protective material 3 on the work alignment member 17, arranging the heat insulating cylinders 2 thereon, and placing the protective material 3 thereon. With a simple operation of pressing the pressing table 22, the rotating table 13 is rotated in this state, the soft packaging material 1 is wound around the heat retaining cylinder 2 and the protective material 3, and then the completed package is pulled out upward. Thus, the package 1 can be formed, and the heat insulation cylinder can be packaged with high productivity.
