  The conventional transport material described in Patent Document 1 has no particular problem in packing and transporting small parts such as automobile handles. However, there are some inconveniences when parts packed and carried in an automobile assembly factory or the like are carried to an assembly work line or the like. In other words, conventionally, this type of transporting material accommodates a plurality of parts in which a plurality of parts are assembled so as not to interfere with each other using a plurality of foamed resin or cardboard cushioning members. It is normal to use a single package, and an assembly factory that is a transport destination first needs to unpack the outer case. In addition, when unpacked, the parts and the cushioning members will be in a disjointed state, so either bring them into the assembly line one by one, or place the parts on the appropriate transport vehicle again. A plurality of them are re-introduced and the work efficiency is lowered.

  In recent automobile assembly factories and the like, high production efficiency is required, and the above-described decrease in work efficiency is a matter to be solved. An object of the present invention is to solve the above-described case. More specifically, the packaging and unpacking operations are easy, and the feeding to an assembly line or the like after the unpacking is efficiently performed. It is an object of the present invention to provide a more improved foamed resin packaging material and a packaging body using the same.

  The invention according to claim 1 is a packaging material made of foamed resin, comprising two substrate materials having receiving grooves for parts to be packaged on at least one surface, and a gripping material formed with a locking portion. It is characterized by that.

  The invention according to claim 2 is the packaging material according to claim 1, wherein the length of the gripping material is based on two substrates when the substrate to be packed is sandwiched between two substrate materials. It is characterized by being approximately equal to the distance between the outer surfaces of the plate material.

  The invention according to claim 3 is the packaging material according to claim 1 or 2, wherein at least a holding portion of the gripping material on the side edge side of the two substrate materials is engaged with the gripping material. A notch having a depth corresponding to the thickness of the locking portion is formed.

  The invention according to claim 4 is the packaging material according to any one of claims 1 to 3, wherein a part to be packed is a handle of an automobile, and two substrate materials are part of the handle. A plurality of receiving grooves parallel to each other in a shape in which is inserted is formed in a direction orthogonal to the side surface side.

  The invention according to claim 5 is a packaging body using the packaging material according to any one of claims 1 to 4, wherein a part of the parts to be packed in a standing posture is formed on the substrate material. In a posture sandwiched between two substrate materials in a posture of entering into the receiving groove, the free movement of the two substrate materials is restricted by engaging the engaging portions of the gripping material on both side edges thereof. It is characterized by being positioned in a state.

  In any of the inventions, the foamed resin constituting the substrate material and the gripping material of the packaging material is not particularly limited. However, from the viewpoints of excellent moldability and recyclability and economical efficiency, a polystyrene foam resin is preferable. The expansion ratio is preferably about 50 times (0.020 g / L) because both the buffer property and the light weight are satisfied. When the part to be packed is an automobile handle, the thickness of the substrate material and the gripping material is desirably about 17 mm or more at the thinnest place when the expansion ratio is about 50 times. If it is thinner than 17 mm, the members (substrate material and gripping material) may be damaged.

  The packaging material according to claims 1 to 4 is entirely made of a resin foam, and a packaging material having required strength and buffering properties can be obtained while being lightweight. Each member can be separated and assembled, and when not in use, the packing materials can be sent to the packing place in a compact state. It can also be reused. The packaging material according to claim 4 is particularly excellent as a packaging material for simultaneously packaging and transporting a plurality of automobile handles.

  The packaging body according to claim 5, wherein the packaging material using the packaging material according to claim 1 is such that the packaged parts are stably supported by two substrate materials, and the two substrate materials are It is possible to take a self-supporting state in which the free movement is restricted by the gripping material locked to both side edges. Therefore, it can be used for storage and transport as it is without using an exterior case as in the prior art. Since an outer case is not required, the packaging work can be simplified. Preferably, the two board members are arranged above and below the parts to be packed.

  In addition, the load in the direction perpendicular to the substrate material can be received by the gripping material, and the load in the direction parallel to the substrate material can be received by the substrate material itself, so the packaging has been stacked in any direction Even in this case, the packaged parts are not overloaded and the parts are not damaged.

  In unpacking, the left and right gripping materials are removed, and the upper substrate material is removed. In this state, the packaged parts are stable in a standing posture in which a part is inserted into a receiving groove formed in the lower substrate material. Therefore, a plurality of parts accommodated in one package can be carried as they are to, for example, an assembly line, and the parts can be arbitrarily taken out from the assembly line. The unpacking operation is easy even when the packaged package is carried into an assembly line or the like and unpacked there. In any case, high production efficiency can be obtained as compared with the conventional packing material.

  In the packing body according to claim 5 and using the packing material according to claim 2 or claim 3, the gripping material does not protrude greatly beyond the level of the outer surface of the two substrate materials. In particular, in the packaging body using the packaging material according to claim 3, at least a place where the holding portions of the holding material are engaged on the side edges of the two substrate materials corresponds to the thickness of the holding portion of the holding material. Since the notch of the depth is formed, both ends of the gripping material can be positioned at the same level as or lower than the outer surfaces of the two substrate materials. Therefore, it is possible to stably stack the packing bodies in a multi-stage and stable posture with the upper and lower substrate material sides as support surfaces.

  The packaging body according to claim 5 and using the packaging material according to claim 4, the packaging body can simultaneously pack and transport a plurality of automobile handles.

  According to the present invention, packing and unpacking operations are easy, and more improved packaging materials made of foamed resin, which can efficiently carry parts into an assembly line after unpacking, and A package using the same is obtained.

  Hereinafter, the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is an exploded perspective view showing an embodiment of a packaging material made of foamed resin according to the present invention, FIG. 2 is a diagram for explaining a packaging procedure during packaging, and FIG. 3 is a diagram showing the packaging material shown in FIG. It is a side view which shows the formed packaging body used.

  The packaging material A shown in FIG. 1 is composed of two substrate materials 10 and 20 made of foamed resin and four gripping materials 30 made of the same foamed resin (note that the gripping material 30 is shown in FIG. 1). Shows only two). In this example, the two substrate materials 10 and 20 have substantially the same shape. The board | substrate material 10 (20) is a rectangular-shaped flat plate as a whole, the surface 11 used as the outer side at the time of packing is a flat surface, and the curved part 13 is formed in the surface 12 used as an inner side. A plurality of (six in the figure) receiving grooves 14 into which a part of a part 1 to be packed (in this example, an in-transit article such as an automobile handle) can enter are provided in the bending portion 13. They are formed parallel to each other along the portion 13. The interval between the adjacent receiving grooves 14 and 14 is set so as not to contact each other in consideration of the shape of the article to be packed.

  On both side edges of the substrate material 10 (20), two concave grooves 15 are formed on each side edge, and a depth a is cut around the outer surface 11 side of each concave groove 15. A notch 16 is formed.

  On one end side of the substrate material 10 (20), a through hole 17 having a size that allows the operator's hand to enter is formed, and is used when carrying the package B or the like. Further, in the illustrated example, a portion indicated by reference numeral 18 is a meat stealing portion, and is formed at an appropriate position of the substrate material 10 (20) on condition that a required strength can be maintained for the purpose of reducing the material.

  The four holding members 30 have the same shape. The holding member 30 has a column main body 31 and locking portions 32 integrally formed at both ends thereof. The cross-sectional shape of the column main body 31 is a shape that can enter the concave groove 15 formed in the substrate material 10 (20). Preferably, the thickness of the column main body 31 is set to the depth of the concave groove 15. equal. The length of the gripping material 30 is equal to the distance between the outer side surfaces 11 and 11 of the upper and lower substrate members 10 and 20 when the component 1 to be packed is sandwiched from above and below, and the above-mentioned locking The planar view shape of the portion 32 is substantially equal to the planar view shape of the notch portion 16 formed in the substrate material 10 (20). Further, the thickness of the locking portion 32 is equal to the depth a of the notch portion 16. Moreover, the part shown with the code | symbol 33 in a figure is a meat stealing part, and is formed in the suitable place of the holding | grip material 30 on condition that required intensity | strength can be hold | maintained for the purpose of material reduction.

  The packing procedure will be described with reference to FIG. First, one substrate material 10 of the two substrate materials 10 (20) is placed in the work place with the flat outer surface 11 as a lower surface. Next, a required number of parts 1 (ring-shaped articles such as handles) to be packed are placed in the receiving grooves 14 formed on the inner side surface 12 and placed in a necessary number. Thereby, the parts 1 to be packed are held in parallel with each other while maintaining the standing posture.

  Next, the other substrate material 20 is placed on the component 1 to be packed, which is held in a standing position, with the receiving groove 14 side as the lower surface side. Thereby, the component 1 to be packed in a standing posture is sandwiched from above and below by the two upper and lower substrate members 10 and 20. The operator places the upper and lower substrate members 10 and 20 in a substantially parallel posture, and uses the concave grooves 15 formed in the respective substrate members 10 and 20 to hold the two grips on each side surface from both side surfaces thereof. The material 30 is attached. As a result, the two substrate members 10 and 20 are brought into a posture in which the engaging portions 32 of the gripping member 30 are engaged in the notches 16 formed on both side edges thereof, whereby two upper and lower substrate members are formed. 10 and 20 are positioned in a state where the free movement is restricted, and become a package B.

  The package B is firmly assembled as it is due to the frictional force between the substrate materials 10 and 20 and the gripping material 30, and is not freely disassembled. Moreover, as shown in FIG. 3, the upper and lower surfaces of the package B are flat surfaces and can be easily stacked. Even when stacked, the gripping material 30 receives the load from above, so that the packaged component 1 is not overloaded. One package B or a package B stacked in a required number is transported to an automobile assembly factory, for example. On the side receiving the package B, it can be stored as it is.

  In unpacking, the four holding members 30 locked to the left and right are removed by pulling sideways, and then the upper substrate member 20 is removed. In this state, the packaged component 1 can maintain a stable standing posture in which a part of the component 1 enters the receiving groove 14 formed in the lower substrate material 10. Therefore, the worker can move the packed parts 1 such as a handle to an assembly line or the like in a posture while riding on the board material 10.

  The packaging material A described above is one preferred form and is not limited to this. In the case where stacking is not necessary, the outer surface 11 of the upper substrate material 20 may not be a flat surface. Further, the gripping material 30 may also include a locking portion 32 that can be engaged with the side surfaces of the upper and lower substrate members 10 and 20 when the component 1 to be packed is sandwiched from above and below, The notch 16 having a depth corresponding to the thickness of the locking portion 32 formed on the side edge side of the substrate materials 10 and 20 can be omitted. Further, the length of the gripping material 30 may be longer than the distance between the outer surfaces of the two substrate materials when the component 1 to be packed is in the posture in which the upper and lower substrate materials 10 and 20 are sandwiched.

  Further, in the illustrated example, the receiving groove 14 is orthogonal to the side edge of the substrate material, but may be inclined. Furthermore, a ring-shaped article such as a handle as the part 1 to be packed is also an example, and the part to be packed may be a rectangular article or the like. In that case, the shape of the inner side surface 12 of the substrate materials 10 and 20 and the shape of the receiving groove 14 are appropriately set according to the shape of the article.
