Description

The present invention relates to a packaging member used for softly covering a corner portion of a product cargo and binding and protecting the product cargo with a rope. Specifically, it covers soft corners of cardboard boxes, cardboard, brittle bricks, gypsum boards, and various other plate materials that are formed by laminating various rectangular parallelepiped product cargos, and then ties them together with straps The present invention relates to a distribution packaging angle member used for protection.

Conventionally, products such as plate materials are laminated, or corrugated boxes, plastic cases, etc. packed with products are laminated on a pallet and stored or transported as product cargo. In this case, various product cargos are bundled together and wrapped with ropes, belts, or the like, or collapsed by preventing the cargo from collapsing by winding the pallet and the product cargo together with a stretchable plastic material called a stretch film.

By the way, after laminating products such as cardboard boxes, plastic cases, various plate materials, etc., when tightening using a strap, such as a rope, a belt, or a stretch film, the tightening force tends to be excessive. For this reason, there is a risk that a rope or belt may bite into the corners of the rectangular parallelepiped formed by laying and damage the product cargo. In addition, if soft cardboard, brittle brick, gypsum board, or the like is strongly tightened, it will be broken and packing will be difficult. In addition, when the stacking height is high, there is no problem in the portion where the stretch film or the like is wound, but the product layer is easily peeled off from the product layer at a portion exceeding the height.

In order to solve these problems, various ideas have been made, and the invention relating to the following physical distribution packaging member has been proposed. The present invention covers a corner of a cylindrical product, and protects the corner of the cylindrical product that is bound and packed by a band from the top, and the configuration is a short piece that is bent from a fold line portion. And an angle member formed by adhering a plurality of layers of plate members each having a long piece, a plurality of V-shaped notches formed in the short piece, and the long piece extending in a direction perpendicular to the folding line. A plurality of grooves are formed (Patent Document 1).

Conventionally, those made of steel, rubber, styrene foam or corrugated cardboard are known as such distribution packaging members for protecting the corners of product cargoes, but there are advantages and disadvantages in terms of physical properties and workability. Recently, plastic products have also been used, and while the problem of exhaustion of earth resources such as oil has become serious, the effective use of waste plastic materials with excellent recyclability has been called out.

Japanese Utility Model Publication No. 5-658

As described above, as represented by Patent Document 1, the conventional distribution packaging member has the following problems.

That is, the first problem of the conventional distribution packaging member is that if the tie is tightened too much, the rope will bite into the corner of the product cargo and damage and deform the cardboard box. In addition, in the case of brittle bricks, gypsum boards, etc., they will break if tightened strongly. In addition, when the stacking height is high, there is no problem in the portion where the stretch film or the like is wound, but the quality of the product cargo cannot be guaranteed, for example, a plurality of layers may be separated from each other and the load collapses easily. In addition, there is a risk that the rope will loosen and collapse when the rope breaks due to friction with the product cargo during the transportation period, or when the power to bind the rope is insufficient.

Secondly, since the conventional distribution packaging member requires pressure resistance or a complicated shape, the productivity tends to deteriorate and the cost tends to increase in order to satisfy these requirements.

Therefore, the distribution packaging angle member of the present invention was made in order to solve such a conventional problem, and is a right angle angle distribution packaging member that matches the corner of a substantially rectangular parallelepiped product cargo. The purpose is to provide a logistics packaging angle member that has a pressure resistance, is excellent in durability, and is inexpensive by selecting a material suitable for this manufacturing method based on a long product obtained by extrusion molding. .

The inventors of the present invention pay attention to the fact that the shape of a cargo product that is often distributed is a substantially rectangular parallelepiped, and the distribution packaging member has an angle shape that matches the corner of the rectangular parallelepiped, and the method of manufacturing this is a long product. Developed into the idea that extrusion molding is easy to obtain. When an angle member was prototyped based on this idea, it was found that a superior pressure strength and cost were obtained, and that corners of product cargo could be sufficiently protected. The distribution packaging angle member of the present invention is embodied on the basis of such knowledge, and the device of claim 1 is formed by laminating a plurality of products to form a substantially rectangular parallelepiped, and matches the shape of the ridge line portion of the substantially rectangular parallelepiped. An angle member having an L-shaped cross section, which is provided with a stripe or a wavy pattern in the longitudinal direction of the surface of the angle member. Further, in addition to the above feature of the invention of claim 1, the angle member is formed by mixing an inorganic filler into a plastic material, and the angle member has a hollow cross section. Further, the angle member is characterized in that a plurality of ribs are formed substantially upright on the surface of the angle member in the cross section. The invention of claim 3 is a physical distribution packaging angle member characterized in that, in addition to the above feature of the invention of claim 2, the plastic material is a waste plastic material.

Here, the “packaging carrier” in the present specification means a cargo of a laminated product that is wrapped and wrapped with a rope, string, band or the like for transportation. For example, in the process of production, transportation, rotation, logistics, etc., put a product into a container such as a cardboard box, a plastic case, etc., and stack a rectangular parallelepiped lump formed with these containers with a rope, string, band, etc. There is a bound packaging carrier. Alternatively, there is a packaging carrier in which products such as laminated plate materials and raw materials are directly put in a container without being put in a container, and tied with a cord band such as a rope, a string or a band.

Since the present invention is constructed as described above, softly and easily damaged corrugated cardboard boxes, cardboard, or brittle bricks, plasterboards, etc. are laminated in a rectangular shape to softly cover the corners of the product cargo. Therefore, it can be effectively used as a physical distribution packaging member when packaging with band tightening. And when manufactured using plastic materials as distribution packaging angle members, it is easy to obtain long products, can be cut and used at any time according to the size of the product cargo, durable and inexpensive Recycling is also possible. In addition, since the cross section is hollow and the ribs are provided in the longitudinal direction, it has a high flexibility and can withstand the force of tightening with the strap. In addition, since waste plastic material can be used, it contributes to the depletion of petroleum resources. Further, using the distribution packaging angle member of the present invention, a brittle gypsum board or an extremely soft board can be packed firmly and inexpensively, and therefore, it can be transported over a long distance by a railway, a ship or a large truck.

Embodiments of the present invention will be specifically described below based on examples of the present invention shown in the accompanying drawings.

First, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing an embodiment of a packing method according to an embodiment of the present invention. FIG. 2 is a perspective view showing a physical distribution packaging angle member used for packing shown in FIG. FIG. 3 is a perspective view showing a surface state of a physical distribution packaging angle member according to another embodiment and viewed from the inside. FIG. 4 is a perspective view as seen from the outside.

FIG. 1 shows a state in which products 2 such as plate materials are stacked and packed, and the stacked rectangular parallelepiped is a packaging carrier 1. An angle member 10 having an L-shaped cross section as shown in FIG. 2 is applied to the long side, short side, and vertical ridge line portion S of the packaging carrier 1. Here, the angle members 15, 15, 15 and 15 are disposed on the ridge line portion S on the long side and the lower side, the angle members 16, 16, 16 and 16 are disposed on the ridge line portions S on the left and right sides of the short side, and further in the vertical direction. The angle members 17, 17, 17 and 17 are brought into contact with the ridge line portion S in accordance with the laminated thickness of the product 2, and the L-shaped angle member is brought into contact with the ridge line portion S of the rectangular parallelepiped. Then, a strap 20 for packing is wound so as to cover from the outside of these angle members. Here, the straps 21 and 21 for packing parallel to the long side, the strap strips 22, 22 and 22 for packing parallel to the short side are wound, and further, these are bent at a right angle to extend in the vertical direction, and a plurality of angles The product 2 is tightened firmly through the member. Thus, each angle member has a function of protecting the corner portion of the product 2 from damage, and the packaging carrier 1 is completed so as to be transportable. In this case, in order to protect the corner K of the packaging carrier 1, any one of the angle members may have a length that reaches the corner K. The angle member described above is obtained by cutting an extruded long material into a short material according to the long side, short side, or laminated thickness of the packaging carrier 1 as needed.

The package carrier 1 packed in this way is exposed to strong winds, and does not collapse even when it encounters severe shaking such as a ship. In addition, it can be piled up in a well-placed girder so that the warehouse and the hold can be used effectively, and cargo handling by forklifts and cranes can be carried out efficiently and safely. In this embodiment, the straps are bound and wound at three locations on the long side and two on each of the short sides and in the vertical direction. The number of straps 20 at these binding sites is the size of the packaging carrier 1. Depending on the strength properties of the product, the weight of the product, the storage location, or the conditions of transportation, it can be selected as appropriate.

The angle member 10 has an L-shaped cross section, and as shown in FIG. 2, the inner angle formed by the inner surface A and the inner surface B is formed at a substantially right angle, and the tip ends of the inner surface A and the inner surface B are rounded. An end R is formed. Further, the cross section of the angle member is hollow, and is provided through the plurality of ribs 11 in the longitudinal direction. The material of the angle member 10 is a long material, which is easily manufactured by extrusion molding, and a long product of 3 meters or more can be obtained, so that the productivity is high. The width dimensions of the inner surfaces A and B may be the same, and depending on the shape of the packaging carrier 1, the width dimensions of the inner surfaces A and B may be varied. Both the inner surface A and the inner surface B are basically flat surfaces, but both may have a surface shape that swells somewhat in an arch shape toward the inner angle side.

As the material of the angle member, there are metal materials such as iron, steel, stainless steel, aluminum alloy and brass in addition to plastic materials, and the dimensions are, for example, about 100 · 100 millimeters of the inner surfaces A and B. The length of the angle member used as a member that protects the corner of the product cargo may be shorter depending on the length of the ridge line portion to be protected, but any one shall be configured to protect the corner. Is desirable. In another embodiment, a cargo handling pallet made of steel, wood or plastic is used on the lower surface side of the product cargo. In this case, it is recommended to use an angle member close to the entire length of the product or a plurality of slightly shorter angle members on the upper surface side of the product cargo. The strap band 20 for packing may be any string such as a strong string, band, rope, etc., but is preferably made of rubber or vinyl.

Next, the operation of the packaging angle member will be described. The cross section of the angle member 10 is a hollow as shown in FIG. In this case, the strength in the thickness direction of the angle member 10 is reinforced by the ribs 11 provided substantially upright with respect to the respective inner surfaces A and B of the angle member 10. Is dispersed and the angle member 10 is flexible enough to bend. Alternatively, due to the elastic restoring force provided by the hollow structure of the plastic material, a spring effect is generated and the string band 20 is prevented from loosening. Further, the angle member 10 is well adapted to the shape of the product 2 due to this bending, and adheres closely thereto. In this way, the angle member 10 overhangs the corner of the product cargo while being tightened by the cord band 20. Further, since the angle member 10 is hollow, the weight is reduced and the amount of plastic material used is also reduced. Further, since the end portion R is rounded, there is no possibility that the cord band 20 at the time of tightening comes into contact with this portion to be worn out or damaged. Further, in the case of an arch shape in which the inner surfaces A and B of the angle members are slightly swollen, the swollen surfaces of the inner surfaces A and B are in contact with each other even if there are irregularities on the side surface of the rectangular parallelepiped shape on which the product 2 is laminated. Tightening force due to is easily applied.

And in FIG. 3, the processing state of the surface seen from the inner side of the angle member 10 which concerns on another Example is shown. On the surface of the angle member 10, as shown in the drawing, a stripe or wavy pattern 12 is provided in the longitudinal direction, and a linear stripe or wavy pattern like a hemp fiber having a fine unevenness is formed. FIG. 4 is a view of the angle member 10 as viewed from the front side, and similarly has a striped or wavy pattern 12 on the surface. When these patterns are manufactured by extrusion molding or pultrusion molding, patterns having fine irregularities in the longitudinal direction, which is the direction in which the material is extruded or drawn, are formed. When the pattern 12 is provided on the inner surface of FIG. 3, the frictional force on the contact surface between the product cargo and the angle member 10 is generated by the striped or wavy pattern 12 to act as a slip, and the angle member 10 is It is difficult to slip off from the ridgeline S of the product cargo. In addition, the striped or wavy pattern 12 and the strap band 20 to be tightened cross each other to reduce the slippage between them. On the other hand, when the pattern 12 is provided on the outer surface of FIG. 4, the strip 12 or the wavy pattern 12 acts to prevent slipping on the contact surface between the angle member 10 and the strap 20, and the strap 20 is separated from the angle member 10 when packing. It is hard to slip and packing work becomes easy.

As described above, in the present embodiment, the products 2 are stacked and directly packed as the packaging carrier 1, but there are various other packing methods. For example, in No. 1, a large number of products are stacked in a rectangular parallelepiped shape on a pallet, and angle members are in contact with the ridges on the long side and short side of the upper surface, and the pallet is packed together from above. Tighten with straps. The second is that many products are stacked in a rectangular parallelepiped shape on the pallet, a plurality of short angle members are arranged on the long side, and the pallet is wrapped with a strap 20 for packing at a plurality of places. Do. The short side and the ridge line portion in the vertical direction are not tightened. No. 3 can be used for the purpose of protecting the lower corner of the product by placing an angle member connected to a rectangular frame at the bottom of the packaging carrier 1. No. 4 is arranged as an angle member at the corner K of the stacked rectangular parallelepiped product, and from the corner K to the three directions of the long side, the short side and the vertical of the rectangular parallelepiped packaging carrier. It is a trident integral type that extends. In this case, since the corner corner portion K of the product 2 in which the angle members are stacked is covered, the corner corner portion K can be prevented from being broken and damaged. In this way, the length of the angle member can be freely selected according to the size and weight of the packaging carrier, the strength of the product 2, and the like, or a rectangular frame integrated type or a trident integrated type can be used.

When a plastic material is used as the material of the angle member, a waste plastic material of the same material can be recycled and used in addition to using a virgin material such as polypropylene, polyethylene, and ABS. Furthermore, in order to reinforce the strength of the angle member, for example, talc, alumina, calcium sulfate gypsum and the like obtained by finely pulverizing talc are mixed in the plastic material as an inorganic filler. Using such a material, an angle member having a complicated cross section can be obtained by injection molding, or a long object having a length of 3 meters or more can be obtained by extrusion molding.

Waste plastic material can be effectively used as the material of the distribution packaging angle member of the present invention. The production of plastic materials requires crude oil and large-scale facilities, and crude oil is not infinite. If it is made and discarded, and then made and discarded, it will eventually be exhausted. In view of this, the present invention has attempted to use, as an angle member material, an industrial plastic product that has been discarded once or a plastic waste material that has been collected and recycled. By the way, in order to recycle plastic materials, it is supposed to be sorted and thrown away in the trash bins of stations and stores, but it is the situation that classification and collection can not be done well, and recently, it is mainly to a country with low labor costs Export and sort and collect manually. The sorted waste plastic material is melted and processed into granular pellets, and then various shaped angle members are produced from the pellets. If necessary, an inorganic filler such as talc obtained by pulverizing talc, calcium sulfate gypsum and the like is mixed into the plastic material for strength reinforcement. There are various types of plastic materials around us, such as polyethylene terephthalate used for plastic bottles for beverages, polycarbonate used for music CDs, polypropylene for plastic bags and candy bags, polyethylene, ABS, etc. It can be obtained inexpensively.

It is a perspective view which shows one Example of the packing method which concerns on the Example of this invention. It is a perspective view which shows the distribution packaging angle member used for packing shown in FIG. It is the perspective view which showed the surface state of the physical distribution packaging angle member which concerns on another Example, and was seen from the inner side. It is the perspective view seen from the outside same as the above.
