Description

  The present invention relates to a packing device, and more particularly to a packing device that packs an article to be packed with a tray and a cushion.

  When delivering goods that are easily damaged by external impacts, such as precision equipment, to store the precision equipment in a cardboard case, a foamed polystyrene resin buffer is placed between the precision equipment and the cardboard case. I try to arrange my body. When an impact is applied from the outside, the impact is absorbed by the foamed resin cushion interposed between the corrugated cardboard case and the precision instrument, so that the impact may be directly transmitted to the precision instrument. This protects the precision instrument from impact.

  Although the foamed polystyrene buffer has a high impact absorption capability, it requires a mold for foam molding, and it is necessary to prepare a mold corresponding to each shape in advance. Accordingly, the cost of the molded body increases due to the mold. In addition, the shock absorber made of styrene foam is not only bulky, but also generates black smoke when discarded and incinerated, and may generate high heat and damage the incinerator.

  Therefore, in Japanese Patent Laid-Open No. 8-34477, Japanese Patent Laid-Open No. 8-252879, Japanese Utility Model Laid-Open No. 7-40537, etc., a buffer body to which cardboard is applied is proposed. Further, the applicants of the present application disclosed in JP 2000-128249 A for the purpose of providing a packaging buffer that can be automatically assembled by a machine and that can be completely recycled. A plurality of cutting lines are formed substantially parallel to each other in a direction perpendicular to the direction extending in the direction, and a plurality of connecting portions are intermittently formed on these cutting lines, whereby a plurality of cardboards are mutually connected. A packaging shock absorber has been proposed that can be folded and alternately folds and troughs at the cutting line and is assembled by joining the corrugated board together.

However, this type of conventional packaging shock absorber is premised on the use of a cardboard case, and the packaging shock absorber is placed in a cardboard case, which is an exterior box, and such a product is protected. In order to do this, a packaging cushion formed by, for example, folding cardboard is disposed between the article and the cardboard case. Therefore, the number of parts of the packaging device is large, and the packaging cost increases.

  According to such a packing apparatus, the article to be packed 10 can be packed with a configuration in which a pair of upper and lower trays 11 and 12 and four types of cushions 13 to 16 or a center cushion 17 are added. In particular, such a packaging device is characterized by the fact that a corrugated cardboard outer box is not used, which greatly reduces the amount of cardboard used. In addition, all parts other than the fastening band 20 are made of corrugated cardboard, and can be recycled, so that the influence of waste pollution can be minimized. In addition, since the upper and lower trays 11 and 12 are used in combination with the corresponding cushions 15, 16 and 13 and 14, respectively, a high buffering effect is exhibited. In particular, since the upper and lower cushions 15, 16 and 13, 14 are respectively connected to the trays 11, 12 by the locking portions 38-40, the trays 11, 12 are weighted with the weight of the articles to be packed. It can be reused without being distorted or deformed.

  32 and 33 show modifications of the trays 11 and 12, which are curved at the upper and lower ends of a pair of cuts 35, 36, and 37 for forming the locking portions 38, 39, and 40, respectively. Portions 41 and 42 are formed. By forming the curved portions 41 and 42 as described above, when the locking portions 38, 39, and 40 are engaged with the corresponding recesses for engagement of the cushions 13 to 16, the cut portions 35 are formed. , 36, 37 are prevented from breaking, and the locking portions 38, 39, 40 can be easily deformed, and a structure that can withstand repeated use can be provided.

  Next, modifications of the cushion will be described with reference to FIGS. Here, the upper rear cushion 16 will be described as an example, but this is a modification that can be applied to the other cushions 13 to 15.

  The basic configuration of the upper rear cushion 16 is basically the same as that of the above-described embodiment shown in FIGS. Therefore, only differences from FIGS. 24 to 28 will be described. As shown in FIG. 34, in this embodiment, a cutting line 45 between the plate-like portions 187 and 188 and a cut between the plate-like portions 189 and 190 are obtained. Four connecting portions 240 are formed on the cutting line 45 between the wire 45 and the plate-like portions 191 and 192 in addition to the connecting portion 60 similar to the above embodiment. Here, the connecting portion 240 is formed on an extension in the direction of the center step of the engagement holes 205 and 206 and the cut 207. Other configurations are the same as those in the above embodiment.

  FIG. 35 shows a state in which the corrugated board shown in FIG. 34 is folded in a zigzag manner, overlapped, glued, joined, and then divided into four at the cutting line 212. It is the same as the form. As shown in FIG. 36, the feature of the four divided upper rear cushions 16 is that the lower surface of the cushion 16 is for engagement formed by aligning the engagement holes 205 and 206 and the notches 207. That is, the connecting portion 240 is positioned on the extension of the concave portion 211. That is, it has the characteristic that the connection structure of the bottom surface by the said connection part 240 was strengthened rather than the said embodiment.
