Description

  The present invention includes a pallet, a board pad placed on the pallet, a plurality of cushioning materials disposed on the board pad, and an exterior box that covers the pallet, the board pad, and the plurality of cushioning materials from above. The present invention relates to a packaging apparatus provided.

  Such a packing apparatus is used as a packing box for transporting relatively large precision machines such as copying machines, printers, and multifunction machines, as described in Patent Document 1, for example. Usually, a cardboard board pad, for example, is placed on a pallet made by combining wooden boards and squares, and a plurality of cushioning materials which are molded products of polystyrene foam are placed thereon. Place the product to be packaged with a protective plastic bag on top of a plurality of cushioning materials, and cover the whole with a cardboard outer box with an open bottom, such as plastic tape or string. Use to fix the pallet and outer box together.

  Moreover, there exists a thing as shown in FIG. 10 as a 1st packing apparatus which inventors know. In this packing apparatus, a square dish-like cardboard pad 102 is placed on a pallet 101, and four cushioning materials 103 to 106 are placed at the four corners thereof. These four cushioning materials 103 to 106 support the bottom four corners of the product to be packed. Note that the products to be packed and the outer packaging are omitted in FIG.

  In this packing device, in order to facilitate positioning of the four cushioning materials 103 to 106, the four sides of the cardboard pad 102 are raised and formed into a square dish shape, so that the thickness increases accordingly. This is an obstacle to reducing the overall size and thickness of the packing material. Further, during the packing operation, the cushioning materials 103 to 106 are lifted or displaced inward, which becomes a factor that deteriorates workability.

  As the second packing device, there is one shown in FIG. This packaging device is intended to improve the disadvantages of the first packaging device shown in FIG. The pallet 101 is the same as that of the first packaging device, but the cardboard pad 112 is a plate-like plate having no rising portions on four sides, and two cushioning materials 113 and 114 placed thereon. Is configured to support the front and rear (or left and right) of the bottom of the product to be packed.

  The pad 112 is formed with holes 112A for positioning the cushioning materials 113 and 114, and columnar protrusions inserted into the holes 112A are formed on the bottom surfaces of the cushioning materials 113 and 114. The outer diameter of the cylindrical projection is set slightly smaller than the diameter of the hole 112A, and a clearance is secured between them.

  However, due to the clearance described above, even in the second packing device, the cushioning materials 113 and 114 may rise during the packing operation, and the horizontal displacement may occur, resulting in poor workability. In addition, since the cushioning materials 113 and 114 support the front and rear (or left and right) sides of the bottom of the product, as a whole, compared to the cushioning materials 103 to 106 of the first packing device that supports only the four corners. It becomes larger and the cost is increased accordingly.

Japanese Patent Laid-Open No. 7-205989

  In view of the above-described problems, the present invention is a packaging device in which the cushioning material is unlikely to be lifted and misaligned while having the advantages of the first and second packaging devices shown in FIGS. It is an object of the present invention to provide a packaging apparatus capable of improving the packaging workability while reducing the cost by using a pad of a shape and a cushioning material having a minimum size.

  The packing apparatus according to claim 1, a pallet, a plate pad placed on the pallet, a plurality of cushioning materials disposed on the plate pad, the pallet, the plate pad, and the plurality of cushions. An exterior box that covers the material from above, and a plurality of engagement protrusions are formed on the bottom surface of each of the plurality of cushioning materials, and the engagement projections of the cushioning material are inserted into the plate pad. An engagement hole is formed, the engagement hole is formed to be the same size as or slightly smaller than the engagement convex portion, and a plurality of slits are formed radially around the engagement hole. And

  The packaging device according to claim 2 is the packaging device according to claim 1, wherein the pallet includes a positioning member that engages with the cushioning material through a notch portion of the plate pad. And

  The packaging device according to claim 3 is the packaging device according to claim 1, wherein the plate pad is made of cardboard.

  According to a fourth aspect of the present invention, there is provided the packaging apparatus according to the first aspect, wherein lengths of the plurality of slits formed radially around the engagement hole are different depending on a radial direction.

  The packaging device according to claim 5 is the packaging device according to claim 1, wherein the shape of the engagement hole is a circle, an ellipse, or an ellipse.

  The packaging device according to claim 6 is the packaging device according to claim 1, wherein lengths of the plurality of slits formed in the plurality of engagement holes are different depending on positions of the engagement holes. And

  The packing device according to claim 7 is the packing device according to claim 1, wherein the plurality of slits formed in each of the plurality of engagement holes are formed so that an angle between adjacent slits is an acute angle. Further, the number of slits is 5 or more.

  According to the packaging device of claim 1, it is possible to provide a packaging device capable of improving the packaging workability while reducing the cost by using the plate-shaped pad and the cushioning material having the minimum necessary size. it can. That is, even in the case of a plate pad having no four-side rising portions, a plurality of engagement convex portions are formed on the bottom surfaces of the plurality of cushioning materials, and the cushioning material engagement convex portions are inserted into the plate pads. Since the engagement hole is formed, positioning is easy. In addition, since the engagement hole is formed to be the same size or slightly smaller than the engagement protrusion, and a plurality of slits are formed radially around the engagement hole, a plurality of slits are formed in the engagement hole of the plate pad. When each engaging protrusion of the cushioning material is inserted from above, the plurality of portions (tongues) divided by the plurality of radial slits formed around the engaging hole are deformed so as to bend downward. Thus, the engagement protrusion is difficult to be removed from the engagement hole. As a result, the plurality of positioned (temporarily fixed) cushioning materials are less likely to float, so that the workability of the packing operation is improved.

  According to the packaging device of the second aspect, since the pallet is provided with the positioning member that engages the cushioning material through the notch portion of the plate pad, the positioning of the cushioning material with respect to the pallet and the plate pad is further facilitated. And misalignment is unlikely to occur.

  According to the packaging device of the third aspect, since the board pad is made of cardboard, it is advantageous in terms of cost. In addition to the cardboard, a resin sheet or the like can be considered as a material for the plate pad.

  According to the packaging device of claim 4, the plurality of portions (tongue portions) divided by the radial slits are obtained by changing the lengths of the plurality of slits radially formed around the engagement hole according to the radial direction. The deformable amount of can be changed depending on the direction. For example, if the length of the slit in the outer direction is shorter than the length of the slit in the inner direction, the deformable amount of the tongue is smaller in the outer direction than in the inner direction. It becomes difficult to shift outward. Thereby, workability | operativity when covering an exterior box improves.

  According to the packing device of the fifth aspect, since the shape of the engagement hole is a circle, an ellipse, or an ellipse, the buffer pad is provided with the buffer material in the engagement hole as compared with the case of the square hole. When the engaging convex portion is inserted from above, the plurality of portions (tongue portions) divided by the plurality of slits formed radially around the engaging hole are easily deformed uniformly. The engagement between the portion and the engagement hole is performed smoothly and uniformly.

  According to the packaging device of the sixth aspect, the displacement of the cushioning material in the horizontal direction occurs by changing the length of the plurality of slits formed in each of the plurality of engagement holes depending on the position of the engagement hole. Ease can be made different among the plurality of cushioning materials. For example, when the rear side of the product is heavier than the front side, if the slit length of the rear engagement hole is made smaller than the slit length of the front engagement hole, the rear cushioning material will be the front cushioning material. Compared to the above, the horizontal displacement is less likely to occur.

  According to the packing device according to claim 7, the plurality of slits formed in each of the plurality of engagement holes are formed so that the angle between adjacent slits is an acute angle (less than 90 degrees). Therefore, when the engagement protrusions of the cushioning material are inserted into the engagement holes of the plate pad from above, a plurality of slits divided by the plurality of slits formed radially around the engagement holes The portion (tongue portion) is easily deformed uniformly, so that the engagement convex portion and the engagement hole are smoothly and uniformly engaged.

  Below, the packing apparatus which concerns on embodiment of this invention is demonstrated based on drawing. In the following description, the use of terms indicating a specific direction or position (for example, “left and right”, “up and down”, etc.) as necessary is for convenience of description only and limits the technical scope of the present invention. Not what you want.

  FIG. 1 is an exploded perspective view showing the entire packaging apparatus according to the embodiment of the present invention. FIG. 2 is an exploded perspective view showing the main part of the packaging device according to this embodiment. The packing apparatus of this embodiment is used as a packing box for transporting a relatively large precision machine (hereinafter referred to as a product) 10 such as a copying machine, a printer, or a multifunction machine. The board pad 12 placed, a plurality of cushioning materials 13 to 16 disposed on the board pad 12, and an exterior box 17 are provided.

  The pallet 11 is a general one made by combining wooden plates and squares, and square members are fixed to the four corners of the upper surface to form a positioning member 11A. The plate pad 12 is formed by punching corrugated cardboard, but may be formed of, for example, a plastic sheet. Cutout portions 12A that engage with the positioning member 11A of the pallet 11 (escape the positioning member 11A) are formed at the four corners of the plate pad 12, and four engagement holes 12B are formed inside thereof.

  The cushioning materials 13 to 16 are molded products of polystyrene foam, and are formed in accordance with the shapes of the four corners so as to contact and support the four corners of the bottom of the product 10. As shown in FIG. 3, an engagement recess RE that engages with the positioning member 11 </ b> A of the pallet 11 is formed on the lower surfaces of the cushioning materials 13 to 16. FIG. 3 is a perspective view of the right front shock absorber 15 of the plurality of shock absorbers 13 to 16 shown in FIG. 2 as viewed from the bottom surface side. An engagement recess RE is formed at one corner of the lower surface of the cushioning material 15, and a columnar engagement projection PR is formed at the opposite corner.

  As shown by the arrows in FIGS. 1 and 2, the plate pad 12 is placed on the upper surface of the pallet 11, and the cushioning materials 13 to 16 are set thereon. At this time, the engaging projections PR of the cushioning materials 13 to 16 are inserted into the engaging holes 12B of the plate pad 12 to be engaged, and positioning members 11A provided at the four corners of the upper surface of the pallet 11 are the plate pads 12. Are engaged with the engagement recesses RE on the lower surfaces of the cushioning materials 13 to 16 through the notches 12A at the four corners. In this way, when the pallet 11, the plate pad 12, and the cushioning materials 13 to 16 are integrated and the product 10 is placed thereon, the four corners of the lower surface of the product 10 are supported by the cushioning materials 13 to 16. The product 10 is previously covered with a protective plastic bag (not shown). Thereafter, the outer packaging box 17 made of corrugated cardboard whose bottom surface is opened is covered, and the pallet 11 containing the product 10 and the outer packaging box 17 are integrally fixed with plastic tape or a string.

  FIG. 4 is a plan view of the plate pad 12. The aforementioned notches 12A are formed at the four corners of the plate pad 12, and four engagement holes 12B are formed inside them. The diameter of the engagement hole 12B is set to a value that is the same as or slightly smaller than the outer diameter of the engagement projection PR of the cushioning materials 13 to 16, and a plurality of (in the illustrated example, 12) around the engagement hole 12B. The slits 12C are formed radially.

  Therefore, when the respective engaging projections PR of the cushioning materials 13 to 16 are inserted into the engaging holes 12B of the plate pad 12 from above, the plurality of slits 12C formed radially around the engaging holes 12B. Since the plurality of divided portions (tongue portions) 12D are deformed so as to bend downward and engage around the engaging convex portion PR, the engaging convex portion PR is difficult to be removed from the engaging hole 12B. As a result, the plurality of cushioning materials 13 to 16 that are positioned (temporarily fixed) are less likely to be lifted, so that the workability of the packing operation is improved.

  In the example shown in FIG. 4, twelve slits 12C are radially formed around the engagement hole 12B at equal angular intervals, but the number of slits 12C can be changed as appropriate. FIG. 5 shows an example in which the number of slits 12C is changed. FIG. 5A, FIG. 5B, and FIG. 5C show examples in the case where the number of slits 12C is 12, 8, and 6, respectively. However, it is preferable to form five or more slits 12C radially at equal angular intervals so that the angle between adjacent slits becomes an acute angle (less than 90 degrees). Accordingly, the plurality of portions (tongue portions) 12D divided by the plurality of slits 12C are easily deformed uniformly, and therefore the engagement protrusion PR and the engagement hole 12B are smoothly and uniformly engaged. When the number of slits 12C is 4 or less, that is, when the angle between adjacent slits is 90 degrees or more, the possibility that the plurality of tongue portions 12D are not uniformly deformed increases.

  4 and 5, the four engagement holes 12B formed in the plate pad 12 are circular. However, the shape of the engagement holes 12B is not limited to a circle but may be an oval or an ellipse. May be. FIG. 6 shows a modification in which the shape of the engagement hole 12B is an oval. If the shape of the engagement hole 12B is a circle, an ellipse, or an ellipse, the engagement protrusions PR of the cushioning materials 13 to 16 are located above the engagement hole 12B of the plate pad 12 as compared to the case of a square hole. Are inserted into the plurality of slits 12C formed radially around the engagement hole 12B, the portions (tongue portions) are easily deformed uniformly, and thus the engagement protrusion PR is associated with the engagement protrusion PR. Engagement with the joint hole 12B is performed smoothly and uniformly. In addition, when the shape of the engagement hole 12B is an ellipse or an ellipse, it is preferable that the cross-sectional shape of the engagement convex part PR also be an ellipse or an ellipse according to it.

  In the example shown in FIGS. 4 and 5, the lengths of the plurality of slits 12C formed radially around the four engagement holes 12B formed in the plate pad 12 are all the same. The length of the slit 12C may be changed. Such a modification is shown in FIG. In the board pad 12 of this modified example, the length of the slit 12C (12C2) going outward is shorter than the length of the slit 12C (12C1) going inward in the front-rear direction (vertical direction in FIG. 7). A plurality of slits 12C around each engagement hole 12B is formed. Thereby, since the deformable amount of the plurality of portions (tongue portions) divided by the plurality of slits 12C is smaller in the outer direction than in the inner direction, the horizontal position of the cushioning material is difficult to shift outward. Thereby, workability | operativity when covering an exterior box improves.

  Further, as in still another modification shown in FIG. 8, the length of the slit 12C may be changed depending on the position of the engagement hole 12B. In the plate pad 12 of this modification, the length of the plurality of slits 12C3 formed around the rear (upper) engagement hole 12B in the front-rear direction (vertical direction in FIG. 8) is the front (lower) engagement. The length is shorter than the length of the plurality of slits 12C4 formed around the joint hole 12B. As a result, the rear two cushioning materials 13 and 14 are less likely to be displaced in the horizontal direction than the front cushioning materials 15 and 16. Such a modification is effective, for example, when the rear side of the product 10 is heavier than the front side.

  The embodiment of the present invention described above is merely an example, and is not limited to the modifications described as appropriate in the description, and various modifications are possible. For example, the packaging device of the present embodiment is configured to support the four corners of the bottom of the product 10 with four cushioning materials 13 to 16, but the scope of the present invention is limited to the packaging device having such a structure. Do not mean. For example, as in another embodiment shown in FIG. 9, the packaging device has a structure in which both front end portions of the bottom of the product 10 are supported by two cushioning materials 15 and 16 and the rear side is supported by one cushioning material 20. The present invention can also be applied to.

  FIG. 9 is a perspective view showing a main part of a packaging device according to another embodiment, in which a plate pad 12 is placed on a pallet 11, and three cushioning materials 15, 16, and 20 are combined thereon. It shows the united state. Also in this embodiment, as in the above-described embodiment, the engagement protrusions PR are formed on the bottom surfaces of the cushioning materials 15, 16, and 20, and the engagement holes 12B into which these engagement protrusions PR are inserted are formed as plate pads. 12, the diameter of the engagement hole 12B is the same as or slightly smaller than the outer diameter of the engagement projection PR, and a plurality of slits 12C are formed radially around the engagement hole 12B, as described above. It is possible to achieve various effects.

  That is, the positioning of the plurality of cushioning materials 15, 16, 20 is facilitated, and the engaging projection PR is difficult to be removed from the engaging hole 12B. Therefore, the plurality of cushioning materials 15, 16, 20 hardly rises and the workability of the packing work is improved. 9 is suitable when the rear side is heavier than the front side of the product 10. That is, the rear cushioning material is not divided into left and right parts, and the entire bottom part of the rear side of the product 10 is supported by one cushioning material 20. It becomes easy to endure deformation. Conversely, when the front side of the product 10 is heavy, the entire bottom portion on the front side may be supported by one cushioning material. Moreover, what is necessary is just to comprise so that the whole bottom part of the heavier side (left side or right side) may be supported by one shock absorbing material, when there is a weight deviation in the left-right direction of the product 10.

  Although the embodiments of the present invention and the modifications thereof have been described above, the shape and structure of each part are not limited to the specific ones described with reference to the drawings, and do not depart from the spirit of the present invention. Various changes can be made.
