Description

  The present invention relates to a packaging technique for a cylindrical body made of a fiber material that is easily crushed, such as a heat insulating cylinder made of inorganic fiber.

  Some heat insulating cylinders made of inorganic fibers such as rock wool and glass wool are liable to be crushed when compressed, and it is necessary to prevent damage from being crushed during transportation. In particular, since the heat insulating cylinder is attached to the pipe in a form in which the end portions are abutted with each other, damage to the end portions must be avoided. Therefore, cardboard box packing is used as the present packing form of the heat insulating cylinder. However, corrugated cardboard boxes require a cardboard box that completely accommodates the heat insulation cylinder, which increases the packaging cost. Moreover, since the unpacked cardboard box becomes garbage at the construction site, a large amount of garbage is generated. There was a problem.

  Therefore, a packaging form that replaces cardboard box packaging is desired. As a packaging technique for stick-shaped articles, which are not packaging of heat insulation cylinders, Japanese Patent Application Laid-Open No. 52-54591 discloses that a plurality of stick-shaped articles are stacked and aligned on a U-shaped guide, and at both end positions of the aligned articles. A method of assembling a cap from cardboard, covering both ends of the article with the cap, and packaging with a shrinkable film thereon is described in Japanese Patent Publication No. 62-4294. Since the method of aligning with a character-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 packaging of a heat insulating cylinder.

However, the packaging method described in Japanese Patent Application Laid-Open No. 52-54591 has a problem that productivity is not good because caps at both ends are assembled in a state of being stacked on a U-shaped guide. Further, in the packaging method described in Japanese Patent Publication No. 62-4294, there is no protective material at both ends of the formed package, so that there is a risk of damage when the package is handled with its ends up and down. there were.

Packaging with good productivity by winding It can be. The packaging materials used in this packaging method are also only a binding material for temporarily fixing a plurality of cylindrical bodies, protective materials at both ends, and soft packaging materials. It is possible to reduce the amount of dust generated and reduce the amount of dust generated. Furthermore, since the obtained packaging body has a protective material at the end of the cylindrical body, the end of the cylindrical body is damaged even when the packaging body is placed vertically. The effect that there is nothing is obtained.

In the invention according to claim 3 , by using a stretch film having large elongation and self-adhesiveness for packaging, the stretch film is wound around the cylindrical body and the protective material disposed on both end faces thereof. Thus, it is possible to easily carry out tight packaging in accordance with the shape of the packaged article, and the obtained package can obtain an effect of being less likely to collapse.

In the invention which concerns on Claim 5 , by making the said cylindrical body into the heat insulating cylinder made from an inorganic fiber, a heat insulating cylinder can be provided with a protective material on both end surfaces, and it can package with a soft packaging material.

  The object of packaging in the present invention is arbitrary as long as it is a cylindrical 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 tube shape. In this specification, the cylindrical body is not limited to a hollow structure, but includes a solid structure. As a typical example of the cylindrical body, a heat insulating cylinder made of inorganic fibers such as rock wool and glass wool can be given. Hereinafter, an embodiment of the present invention will be described by taking a heat insulating cylinder as an example.

  FIG. 1 shows an example of a package formed by the packaging method of the present invention. The whole package denoted by reference numeral 1 is a package of a plurality of heat insulating cylinders 2 made of inorganic fibers. The plurality of heat insulating cylinders 2 are in contact with the body and as shown in FIG. 1 (c). Are arranged so as to form a quadrangular shape, plate-like protective materials 3 are applied to both end faces of the arranged heat insulating cylinders 2, and a film-like soft packaging material 4 is provided around the plurality of heat insulating cylinders 2 and the protective materials 3. It is wound and integrated as a whole. The protective material 3 used here is for protecting the end face of the heat insulating cylinder 2, and has a size capable of covering the end faces of the plurality of heat insulating cylinders 2 to be packaged together and has a strength necessary for protection. Things are used. Further, the protective material 3 is preferably lightweight and can be easily disposed of such as disposal. Specifically, paper cardboard is suitable. The planar shape of the protective material 3 is a quadrangle in accordance with the arrangement of the plurality of heat insulating cylinders 2 in FIG. It should be noted that the corners of the protective material 3 may be modified so as to be cut obliquely so as not to protrude or to have an arc shape in accordance with the shape of the heat insulating cylinder 2. Furthermore, the protective material 3 is not limited to a flat plate, and the heat insulating cylinder 2 is provided on the periphery of the flat portion 3a pressed against the end surface of the heat insulating cylinder 2 as in the protective material 3A used in the package 1A shown in FIG. It is good also as what provided the upright wall part 3b for protecting the outer peripheral surface of this edge part. The upright wall portion 3b is not limited to being provided on the entire circumference of the flat portion 3a, but may be modified such as being provided in a partial region or a plurality of regions on the periphery of the flat portion 3a. The protective material 3A in this form can be easily formed by bending a plate material such as corrugated 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 they can wrap the heat insulating tube 2 and the protective material 3 integrally. A film, a laminated film, paper, etc. can be illustrated. Moreover, in the drawing, the entire length of the heat insulating cylinder 2 is wrapped by winding the soft packaging material 4 having a narrow width in a spiral shape so as to partially overlap. However, the length of the heat insulating cylinder 2 is not limited to this form. Alternatively, packaging may be performed using a wide width soft packaging material. At both ends of the heat insulating cylinder 2, the soft packaging material 4 is wound so that a part of the width direction extends outward from the protective material 3 (on the side opposite to the heat insulating cylinder 2). The part 4 a in the width direction of the packaging material 4 is wound around the outer surface of the protective material 3, and the protective material 3 can be kept fixed to the heat insulating cylinder 2. If necessary, a part 4a of the soft wrapping material may be attached to the protective material 3 using an appropriate means such as an adhesive tape or an adhesive. When using a resin film as the flexible packaging material 4, it is preferable to use a stretch film or a heat-shrinkable film. Stretch film usually has large elongation and self-adhesiveness, so it is tightly wrapped according to the shape of the heat insulation cylinder 2 and the protective material 3 just by winding the stretch film around the heat insulation cylinder 2 and the protective material 3 with an appropriate tension. In addition, since the heat insulating cylinder 2 and the protective material 3 are tightly packaged with the stretch film in the obtained package, it is possible to prevent the collapse of the load during transportation for a long period of time. When the heat-shrinkable film is used, the heat-insulating cylinder 2 and the protective material 3 can be tightly packaged by heat-shrinking after packaging, and the collapse of the load during transportation can be prevented over a long period of time.

  Next, a packaging method and a packaging apparatus for forming the package 1 having the above-described configuration will be described. FIG. 3 is a schematic cross-sectional view of the packaging device 10 as viewed from the side, FIG. 4 is a schematic front view showing the cradle 11 of the packaging device 10 shown in FIG. 5 is a schematic front view showing the film winding device 18 of the packaging device 10 shown in FIG. 3 in a state when the flexible packaging material 4 is wound around the heat insulating cylinder 2, and FIGS. 6 (a), 6 (b) and 6 (c) are packaging. FIG. 4 is a schematic cross-sectional view showing a packaging operation by the device 10. 3 to 6, reference numeral 11 denotes a cradle for arranging a plurality of heat insulating cylinders 2 in a predetermined arrangement. The cradle 11 has a length that supports substantially the entire length of the heat insulating cylinder 2 and, as shown in FIG. 4, has a substantially U-shaped cross section so that a plurality of the heat insulating cylinders 2 can be arranged in a square shape. Is. Note that the cradle 11 is not limited to the one that supports the entire length of the heat insulating cylinder 2, and may be shorter than the heat insulating cylinder 2 as long as it can support the heat insulating cylinder 2 in a state where it is not bent. Alternatively, it may be configured to be divided into a plurality of parts so as to support a plurality of positions in the longitudinal direction of the heat insulating cylinder 2.

  3 to 6, reference numeral 13 denotes a heat insulating cylinder 2 arranged by pressing the protective material 3 applied to both end faces of the plurality of heat insulating cylinders 2 supported by the cradle 11 against the end faces of the heat insulating cylinders 2 from the outside. This is a workpiece restraint moving device for restraining the crucible so as not to collapse and moving the protective material 3 and the heat insulation cylinder 2 in the longitudinal direction in a restrained state so as not to collapse and taking them out from the cradle 11. The work restraint moving device 13 includes a work pressing member 14a for pressing the protective material 3 arranged on one end face of the heat insulating cylinder 2 arranged in the cradle 11 against the heat insulating cylinder 2, and the work pressing member 14a. The first pusher 14 provided with a cylinder mechanism 14b such as an air cylinder that reciprocates in the longitudinal direction of the heat insulating cylinder 2 in the cradle 11 and the protective material 3 disposed on the other end face of the heat insulating cylinder 2 2 and a second pusher 15 including a cylinder mechanism 15b such as an air cylinder that reciprocates the workpiece pressing member 15a in the longitudinal direction of the heat retaining cylinder 2. Here, the work pressing members 14a and 14b have a considerably smaller area than the protective material 3 so that the protective material 3 can be pressed in a state where the peripheral region of the surface of the protective material 3 facing the workpiece pressing member is exposed. Is made. This means that when the soft wrapping material 4 is wound around the protective material 3, a part of the soft wrapping material is wound on the surface of the protective material 3 [see the part indicated by reference numeral 4a in FIG. 1 (a)]. This is to allow. The means for reciprocating the workpiece pushing members 14a and 14b is not limited to the cylinder mechanism, and other mechanisms such as a mechanism using a motor may be used.

  Reference numeral 18 denotes a film wrapping device for wrapping the soft wrapping material 4 around the plurality of heat insulating cylinders 2. As can be clearly understood from FIG. 5, the film winding device 18 includes a ring-shaped guide 19 disposed so as to surround a region through which the plurality of heat insulating cylinders 2 pass, and a soft guide held movably along the guide 19. The packaging material feeding device 20 and a driving means for moving the flexible packaging material feeding device 20 along the guide 19 are provided, and the flexible packaging material 4 for winding the flexible packaging material feeding device 20 around the plurality of heat insulating cylinders 2. For example, a soft packaging material roll 4A for feeding out a stretch film is held. The soft wrapping material feeding device 20 is also provided with a tension applying means, for example, a brake so that an appropriate tension can be applied to the soft wrapping material 4 to be fed. Reference numeral 22 denotes a guide roller that movably supports the plurality of heat insulating cylinders 2.

  Next, a packaging method by the packaging apparatus 10 having the above configuration will be described. In FIG. 6A, a plurality of heat insulating cylinders 2 are supplied into the cradle 11 manually or using an appropriate transfer robot. The plurality of supplied heat insulating cylinders 2 are arranged in a quadrangular shape following the shape of the inner surface of the cradle 11 as shown in FIG. Next, the protective material 3 is pressed against the both end surfaces of the plurality of heat insulating cylinders 2 in the cradle 11 manually or using an appropriate transfer robot, and then, as shown in FIG. The one pusher 14 and the second pusher 15 are actuated, and the protective material 3 is pressed against the end face of the heat insulation cylinder 2 from the outside by the work pushing members 14a and 14b, and the heat insulation cylinders 2 in the arranged state are restrained so as not to collapse.

  Next, the pressing force of the first pusher 14 is increased in a state where the protective material 3 and the heat retaining cylinder 2 are restrained so as not to collapse by the workpiece pressing members 14a and 14b, and as shown in FIG. 3 and the heat insulating cylinder 2 are pushed in the longitudinal direction and moved out of the cradle 11. And when the front-end | tip reaches the film winding apparatus 18, winding of the flexible packaging material 4 is started. That is, the tip of the soft wrapping material 4 drawn from the soft wrapping material roll 4A set in the soft wrapping material feeding device 20 is placed in the width direction around the tip portion of the heat insulating cylinder 2 and the protective material 3 in contact with the tip. Wrap so that a part is outside the protective material 3 (opposite side of the heat insulating cylinder 2), and then turn the soft packaging material feeding device 20 along the guide 19 while moving the protective material 3 and the heat insulating cylinder 2 forward The flexible packaging material 4 from the flexible packaging material feeding device 20 is wound around the heat insulating cylinder 2. At this time, the flexible packaging material feeding device 20 applies a preset tension to the flexible packaging material 4. As a result, the flexible packaging material 4 is wound around the heat retaining cylinder 2 in a spiral shape and partially overlapping with a predetermined tension. In addition, at the beginning of winding, the portion of the soft wrapping material wound outside the protective material 3 is wound on the outer surface of the protective material 3 by the tension acting on the portion, and the protective material 3 is fixed to the heat insulating cylinder 2. The flexible packaging material 4 is wound up to the rear end region of the heat insulating cylinder 2 and is wound until a part of the width direction of the flexible packaging material is outside the protective material 3 on the rear end side. Thereby, the part of the soft packaging material wound outside the protective material 3 is wound on the outer surface of the protective material 3 by its own tension. Thereafter, the movement of the heat insulating cylinder 2 and the turning of the soft packaging material feeding device 20 are stopped, the soft packaging material 4 is cut, and the end portion is pressed against the surface of the soft packaging material or the protective material 3 which has been wound first. , Fix. At this time, when a stretch film is used as the soft wrapping material 4, it can be bonded by the self-adhesiveness of the stretch film, so there is no need to use an adhesive tape or an adhesive. The part can be easily cleaned up. In addition, what is necessary is just to clean up the edge part of the soft packaging material 4 using an adhesive tape or an adhesive agent, when the soft packaging material 4 is not provided with self-adhesiveness. By the above operation, the package 1 having the form shown in FIG. 1 is created.

  When a heat-shrinkable film is used as a soft wrapping material to wrap the heat insulating cylinder 2, a heating device 25 is provided downstream of the film winding device 18 as shown in FIG. Similarly, the heat-shrinkable film in the wound region may be heated and shrunk while the soft packaging material 4 (heat-shrinkable film) is wound around the plurality of heat retaining cylinders 2. When packaging with a heat-shrinkable film, the heat-shrinkable film can be heat-shrinked after winding, even if the tension at the time of winding the heat-shrinkable film around the plurality of heat insulating cylinders 2 is not so high or tension is not applied. There is no problem because it can be tightened. For this reason, tension adjustment at the time of winding is almost unnecessary, and winding work becomes easy.

  As described above, the packaging method using the packaging apparatus 10 simply puts the plurality of heat insulating cylinders 2 in the receiving base 11, applies the protective material 3 to both end faces thereof, and the protective material 3 by the work restraint moving device 13. Is pressed against the heat insulating tube 2 and restrained so that the protective material 3 and the heat insulating tube 2 are not collapsed, and is sent out from the cradle 11 to the film winding device 18. By the simple operation of winding the soft packaging material 4 around the protective material 3, the packaging body 1 having the form shown in FIG. 1 can be formed, and the heat insulation cylinder can be packaged with high productivity.

  Since the packaging body 1 formed by the above packaging method wraps the heat insulating cylinder 2 only with the protective material 3 and the soft packaging material 4 arranged at both ends, it is far more than the conventional form stored in the cardboard box. It can be packed with a small amount of packaging material, and the packaging cost can be reduced. In transporting and storing, even if the package 1 is placed vertically, the end of the heat retaining cylinder 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 packaging materials, there are various advantages such that the unpacking operation at the construction site is easy and the amount of generated dust can be reduced.

  In addition, in embodiment shown in FIG.6 (c), the film winding apparatus 18 is arrange | positioned near the base 11, and winding of a soft packaging material is started from the middle of taking out the several heat insulation cylinder 2 from the base 11. However, the present invention is not limited to this configuration, and the film winding device 18 is disposed at a position further away from the cradle 11 and the heat insulating cylinder 2 is completely removed from the cradle 11 and then the flexible packaging material is removed. It is good also as a structure which winds. Furthermore, in the above-described embodiment, the cradle 11 is substantially U-shaped as shown in FIG. 4 and the plurality of heat insulating cylinders 2 are arranged in a quadrangular shape. The shape of the table 11 can also be changed as appropriate. Examples are shown in FIGS. 7 (a) and 7 (b). The cradle 11A shown in FIG. 7A is substantially V-shaped, and the heat insulating cylinders 2 can be arranged in a quadrilateral shape therein. Moreover, the cradle 11B shown in FIG.7 (b) is a reverse trapezoid shape, and the thermal insulation cylinder 2 can be arranged in hexagon shape in it.

  Further, in the embodiment shown in FIG. 6, the plurality of heat insulation cylinders 2 are held by pressing the plurality of heat insulation cylinders 2 arranged on the cradle 11 from the outside of the protective material 3 applied to both end surfaces thereof by the work restraint moving device 13. Although it restrains so that it may not collapse, it can also be set as the structure fixed temporarily so that it may not be collapsed by tying the several heat insulation cylinders 2 with the appropriate binding material instead of using together or this. Hereinafter, an embodiment in that case will be described.

  FIG. 8 shows a packaging apparatus 10A used for carrying out a packaging method including a step of winding a plurality of heat insulating cylinders 2 with a binding material and temporarily fixing them. In this packaging apparatus 10 </ b> A, a receiving base 11 </ b> C shorter than the heat insulating cylinder 2 is used as a receiving base for arranging a plurality of heat insulating cylinders 2. Other configurations are the same as those of the packaging device shown in FIG. When packaging is performed by the packaging apparatus 10A shown in FIG. 8, first, as shown in FIG. 8A, a plurality of heat insulating cylinders 2 are supplied into the cradle 11C and arranged so as to have a predetermined arrangement. At this time, the heat insulating tube 2 is set so that both end regions of the heat insulating tube 2 extend outside the cradle 11C. Next, as shown in FIG. 8 (b), the protective material 3 is pressed against both end faces of the plurality of heat insulating cylinders 2, and then the first pusher 14 and the second pusher 15 are operated, and the workpiece pressing member 14a, The protective material 3 is pressed against the heat insulating cylinder 2 from the outside by 14b, and the protective material 3 and the heat insulating cylinder 2 are restrained. The restraining force by the first pusher 14 and the second pusher 15 at this time does not need to be large enough to restrain the heat retaining tube 2 so that it does not collapse when the heat retaining tube 2 is taken out from the cradle 11C. It may be smaller than the case of the embodiment shown in FIG. In this state, the binding material 30 is wound around portions of the both end regions of the plurality of heat retaining cylinders 2 that protrude outward from the cradle 11C, and the plurality of heat retaining cylinders 2 are temporarily fixed so as not to collapse. The binding material 30 used here is arbitrary as long as it can be wound around a plurality of heat insulating cylinders 2 and temporarily fixed so as not to collapse the heat insulating cylinders 2, and examples thereof include films, tapes, strings, bands, and the like. However, it is preferable to use a stretch film because it is easy to wrap and fix. When a stretch film is used as the binding material 30, the stretch film is wound not only on the heat insulating cylinder 2 but also around the protective material 3 pressed against the end surface thereof, and the protective material 3 is wrapped around the heat insulating cylinder 2. It may be fixed. The operation of winding the binding material 30 around the plurality of heat insulating cylinders 2 may be performed manually, or may be performed using an appropriate binding device provided.

  After the binding material 30 is wound around the plurality of heat insulation cylinders 2 and temporarily fixed so as not to collapse, as shown in FIG. 8C, a plurality of heat insulation cylinders are provided as described in the embodiment of FIG. 2 and the protective material 3 on both end surfaces thereof are moved to the film winding device 18, and the flexible packaging material 4 is wound around the heat insulating cylinder 2 and the protective material 3 on both end surfaces by the film winding device 18. The heat insulation cylinder can be packaged with good quality. In this embodiment, before the plurality of heat insulation cylinders 2 are taken out from the cradle 11C, the binding material 30 is wound around the plurality of heat insulation cylinders 2 and fixed so that the plurality of heat insulation cylinders 2 do not collapse. Even if the restraining force by the one pusher 14 and the second pusher 15 is small, the plurality of heat insulating cylinders 2 are not collapsed during movement, and good packaging can always be performed. In the above description, the protective material 3 is applied to both end faces of the plurality of heat insulating cylinders 2 arranged in the cradle 11C, and pressed against the end face of the heat insulating cylinder 2 by the first pusher 14 and the second pusher 15, The binding material 30 is wound around the plurality of heat insulating cylinders 2 and temporarily fixed. Instead, the binding material 30 is first wound around the plurality of heat insulating cylinders 2 and temporarily fixed. The protective material 3 may be applied to both end surfaces, and the first pusher 14 and the second pusher 15 may be used to press against the end surface of the heat retaining cylinder 2. However, before the binding material 30 is wound around the heat retaining tube 2 and temporarily fixed, the protective material 3 is applied to both end surfaces of the heat retaining tube 2 and pressed against the end surface of the heat retaining tube 2 by the first pusher 14 and the second pusher 15. It is preferable to place the plurality of heat retaining cylinders 2 in the longitudinal direction.

  FIG. 9 shows a package 1B created by the packaging apparatus of FIG. 8, and in this package 1B, a plurality of heat insulating cylinders 2 arranged are bound by binding materials 30 at both ends, and further the heat insulating The protective material 3 is applied to both end faces of the tube 2, and the flexible packaging material 4 is wound around the plurality of heat insulating tubes 2 and the protective material 3 so as to be integrated as a whole. Also in this package 1B, since the plurality of heat insulating cylinders 2 are packaged only with the binding material 30, the protective material 3 and the flexible packaging material 4 disposed at both ends, compared with the conventional form stored in the cardboard box. It is packaged with a much smaller amount of packaging material, reducing packaging costs. In transporting and storing, even if the package 1 is placed vertically, the end of the heat retaining cylinder 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 packaging materials, there are various advantages such that the unpacking operation at the construction site is easy and the amount of generated dust can be reduced.

  In the embodiment of FIG. 8, the binding material is wound around both ends of the plurality of heat insulating cylinders 2 held on the cradle 11C and fixed so that the heat insulating cylinder 2 does not collapse. The position for winding is not limited to this, and can be changed as appropriate. For example, like the packaging device 10B shown in FIG. 10, two receiving elements 11a and 11a arranged at intervals are provided as the receiving table 11D. It is good also as a structure which wraps the binding material 30 around the center area | region (area | region located between the two cradle elements 11a and 11a) of the heat insulation cylinder 2 using a thing. Also with this packaging apparatus 10B, as shown in FIGS. 10 (a), (b), and (c), the heat insulation cylinder 2 can be packaged with high productivity in the same procedure as the packaging apparatus 10A shown in FIG. .

  The packaging method of the present invention is extremely suitable for a thermal insulation tube made of inorganic fibers such as rock wool and glass wool, and can be applied to the packaging of the thermal insulation tube to reduce the packaging cost of the thermal insulation tube and to construct the thermal insulation tube. In addition to the heat retaining cylinder, it can be applied to the packaging of any cylindrical body made of fiber material that is easily crushed. is there.
