Description

  The present invention relates to an air-packing device that air-packs articles to be packed such as electronic components and electronic products during transportation.

  When transporting electronic devices such as various electronic components and electronic products, a packing tool is used for packing the electronic device in a state where it floats in the air inside a storage case.

  In the conventional packing tool, a rectangular fold plate is formed around the four sides of the frame plate by attaching a frame crease around the four sides of the rectangular frame plate and a waist fold at a predetermined distance from the frame fold. It is formed. The first waist plate is a rectangular plate having a width from the frame fold to the waist fold, and the second waist plate is a rectangular plate having a narrower width than the first waist plate extending after the waist fold. .

  In addition, a rectangular middle window is formed in the central portion of the rectangular frame plate, and a predetermined length of cut is provided in the radial direction from the four corners of the middle window, and adjacent cut ends are connected to each other. A window plate that is movable in the vertical direction is formed.

  When packaging the electronic device, the first waist plate is bent 90 degrees with respect to the frame plate, and the second waist plate is bent 90 degrees with respect to the first waist plate. Then, the electronic device is accommodated so that the window plate attached to the middle window at the center of the frame plate is pushed downward.

  Further, the same packaging as described above is placed on the upper side of the electronic device in the storage case. That is, the electronic device is sandwiched between two packing tools. Further, after folding the first and second waist plates of the upper packing tool in the opposite direction to the first and second waist plates of the lower packing tool, the lid of the storage case is closed to pack the electronic device. Complete (Patent Document 1).

Furthermore, conventionally, as another packing tool, there is one in which a middle window is formed at the center of a rectangular frame plate and a polyurethane film such as saran wrap is pasted so as to close the middle window. This packing tool is set so as to hold the electronic device on the stretchable polyurethane film part affixed to the middle window, and then covered with a packing tool having the same configuration from the upper side of the electronic device. Hold the electronic device with the packing tool and pack it.

That is, there is a problem that the uneven portion of the electronic device jumps out of the inner window and does not play the role of hollow packaging, and the electronic device is damaged during transportation.

  Also, the former packing method is that when storing electronic devices packed using packing tools in the storage case, elastic thin films, buffer holding frames with foam, and buffer holding with rubber nets are placed below and above the upper and lower packing tools. Since the frame is used, it is necessary to secure a certain space, which increases the cost and increases the size of the storage case.

  On the other hand, the latter packing tool has a polyurethane film attached to an inner window formed on the frame plate. For example, when storing a plurality of electronic components, the central portion of the polyurethane film bulges and this bulge is formed. A plurality of electronic components are gathered in the area. As a result, there is a problem that the electronic components collide with each other when the electronic device is transported and are damaged.

As an optimum material, coated paper having the above characteristics is desirable. Coated paper is a material that has properties such as tension and rigidity, and has high moisture absorption.

  Next, an example will be described in which an article to be packed is air-packed using the packing tool 10 and the cushioning material 30 as described above.

(1) The packing tool 10 and the cushioning material 30 are assembled so as to be housed in a housing case 41 shown in the lower part of FIG. It should be noted that which of the packing material 10 and the cushioning material 30 is assembled first is arbitrary, but an example in which the cushioning material 30 shown in FIG. 3 and the packaging tool 10 shown in FIG.

  As shown in FIG. 3, the cushioning material 30 bends the position restricting plate portions 32 and 32 vertically with respect to the respective cushioning body portions 31 a and 31 b with the folds 35 and 35 as boundaries.

(2) Next, the packaging tool 10 is assembled. As shown in FIG. 4, the packing tool 10 has a first waist plate 23 with respect to the product holding frame plate portion 11 with folds 18,... , 23 and the second waist plates 24, 24 are vertically bent upward. At this time, since the plurality of elongated holes 19,... And the plurality of protruding cuts 20,... Are provided on the line of the creases 18,..., The first waist plates 23, 23 and the second waist plates 24, 24 are compared. It can be easily folded.

(3) After the first waist plates 23 and 23 and the second waist plates 24 and 24 are bent into a tray shape as described above, the position regulating plate portion is already in the tray corresponding to the back surface of the packing tool 10. A cushioning material 30 formed by bending 32 and 32 is disposed. That is, a little pressure is applied to the inside of the tray corresponding to the back surface of the packing tool 10 from both ends of the buffer body portions 31a and 31b in which the position restricting plate portions 32 and 32 have already been bent to apply the buffer body portion 31a. , 31b are overlapped as being slightly bulged.

  As a result, the position restricting plate portions 32, 32 connected to the left and right ends of the buffer body portions 31a, 31b completely overlap, for example, the inner side portions of the first waist plates 23, 23 connected to the left and right ends of the article holding frame plate portion 11. It becomes a state.

  At this time, the protrusions 36,... Applied to the left and right folds 35, 35 of the buffer body portions 31a, 31b are boundary lines between the article holding frame plate portion 11 and the first waist plates 23, 23, respectively. In other words, the cushioning material 30 is prevented from being positioned and displaced with respect to the packing tool 10 by being fitted into the elongated holes 19 opened on the line of the creases 18.

(4) After the position restricting plate portions 32, 32 of the cushioning material 3 and the first waist plates 23, 23 connected to the left and right end portions of the product holding frame plate portion 11 are overlapped as described above, the product holding frame plate The both ends of the second waist plates 24, 24 are connected to the outer sides of the first waist plates 23, 23 via folds 28, 28 attached to both sides of the second waist plates 24, 24 connected to the upper and lower ends of the portion 11. Or bend it vertically so that it overlaps inside. Then, when the both ends of the second waist plates 24, 24 are bent, the inner kerfs 26, 26 provided at both ends of the second waist plates 24, 24 are already overlapped with the outer kerfs of the first waist plate 23. 25 and the outer kerf 38 of the position restricting plate 32 so that the tongue side portions 27 and 27 provided at both ends of the second waist plates 24 and 24 are fitted to the position restricting plates 32 and 32. It will be in the state which overlapped with the inner surface part or the outer surface part of the 1st waist board 23,23.

(5) After that, the fitting pieces 34, 34 connected to the upper and lower peripheral edge portions serving as the boundary between the left buffer body portion 31 a and the right buffer body portion 31 b of the buffer main body portion 30 are arranged in the tray inward direction corresponding to the back surface of the packing tool 10. The cushioning material 30 is completely assembled and integrated into the packing tool 10 by being pressed into the fitting hole 21 of the packing tool 10 (see FIG. 5A). In this way, two packing tools 10 including the cushioning material 30 are prepared.

(6) Further, after storing one packing tool 10 including the cushioning material 30 shown in FIG. 5A in an inverted state in the storage case 40 (see FIG. 5C), the packaging is performed. The article to be packed 50 (see FIG. 5 (b)) is placed on the upper surface of the center of the article holding frame plate portion 11 constituting the tool 10. Then, another packing tool 10 including the cushioning material 30 shown in FIG. 5A is covered from the upper part of the article to be packed 50 and set so as to be sandwiched between the upper and lower packing tools 10 and 10.

  Finally, the upper lids 41 and 42 of the storage case 40 are folded, and the tongue pieces 41a, 41a, 42a and 42a provided on both sides of the upper lids 41 and 42 are folded. When the parts 41 a, 41 a, 42 a, 42 a are pushed into the storage case 40, the packaged product 50 is air-packed in the storage case 40. At this time, since the upper and lower peripheral surface portions of the left buffer body portion 31a and the right buffer body portion 31b constituting the buffer material 30 are respectively provided with tongue pieces 37,... A gap is formed between the packaging material 10 and the tray outer surface into which the material 30 has been inserted, and in particular, the tongue pieces 41a and 41a can be easily pushed into the storage case 40.
