Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a packaging device that improves workability when storing items to be packaged in a packaging box.

[Technical background of the invention]

Traditionally, for example, packaging equipment for refrigerators involves placing a refrigerator on a bottom plate, covering it with a packaging box with an open bottom, and then tying the whole thing with a band. The refrigerator is protected by using cushioning material on the surface.

[Problems with background technology]

In the above configuration, the cushioning material, especially around the surrounding area of the refrigerator, cannot be placed in the specified location after the packaging box is covered, so the cushioning material is pasted with tape to the surrounding area of the refrigerator in advance. In this state, a packaging box is placed over the top. However, since the cushioning material protrudes from the peripheral surface of the refrigerator, the opening edge at the lower end of the packaging box tends to get caught in the cushioning material when the packaging box is placed on the refrigerator. This makes the packaging process very troublesome, especially if the packaging box is forcibly covered, the tape will peel off and the cushioning material will fall off, or some of the cushioning material may be chipped, resulting in insufficient cushioning. There was a risk that it would not have any effect.

1 [Object of the Invention] The object of the present invention is to provide a packaging device that can improve workability when packaging items in a packaging box.

[Summary of the invention]

The present invention has a structure in which a bag is provided in a packaging box with an injection port facing outside the packaging box, and foamed puf stick is injected into the bag through the injection port and foamed to serve as a cushioning material. The purpose is to allow cushioning material to be provided even when the box is placed over the packaged item.

[Embodiments of the invention]

An embodiment of the present invention will be described below as applied to a refrigerator with reference to the drawings. 1 is a wooden bottom plate, 2 is four styrofoam bottom cushioning materials placed on the four corners of this bottom plate 1, and 6 is an article to be packaged placed on the four bottom cushioning materials 2.
Barrel cold d1. It is a warehouse.

As is well known, this refrigerator 3 is provided with a door 4 at the front, a condenser (not shown) attached to the inside of a back plate 5, and a compressor 6 disposed at a rear portion of the bottom. Reference numeral 7 designates upper cushioning materials made of styrofoam that are applied to the right and left edges of the upper part of the refrigerator 3. Reference numeral 8 denotes a cardboard box body of a packaging box with its bottom surface open; this box body 8 is placed over the refrigerator 3 placed on the cushioning material 2 after applying the upper cushioning material 7 thereto. The box body 8 constitutes a packaging box 9 together with the bottom plate 1.

The inlet body is made by Pufstik. This injection port body 10 has an opening at the front end (right end in the drawing) as an injection port 11, and a flange 10a is formed on the peripheral side edge of the front end.
A cap 12 for closing the injection port 11 is integrally formed on the outer peripheral edge via a connecting band 12a. The inlet body 10 is the peripheral surface of the box body 8.

For example, holes 13, 1 are drilled in the back (right side in the figure) at locations corresponding to the vertical center shafts of the left and right side lines of the back of the refrigerator 3:
4 and a hole 15 drilled at a position corresponding to the compressor 6
It is embedded in. A polyethylene bag 16 is attached to the rear end of each inlet body 10 within the box body 8. Reference numerals 17, 18, and 19 are cushioning materials according to the present invention, and these cushioning materials 17 and 18. 19 are made by injecting foamed plastic, for example, foamed urethane, through the injection port 11 and filling the polyethylene bag 16. Then, the injection port 11 was closed with a cap 12 to solidify the urethane foam. The cushioning materials 17 and 18 are located in close contact with both the left and right corners of the back of the refrigerator 3 and the left and right corners of the back of the box body 8 so as to close the space between them, and the cushioning materials 19 is located close to both the rear of the compressor 6 and the back of the box body 8 so as to close the space between the two. In addition, 20 is the bottom plate 1
and a tightening band wound around the box body 8.

Next, the operation of the above configuration will be explained. When packaging the refrigerator 3, first, the bottom cushioning material 2 is placed on each of the four corners of the bottom plate 1, and the refrigerator 3 is placed on the bottom cushioning material 2.

Then, the upper cushioning material 7 is applied to the left and right side corners of the upper part of the refrigerator 5, and in this state, the box body 8, in which holes 13, 14, and 15 are previously formed, is placed over the refrigerator 6 from above. At this time, if you first insert the lower end of the box body 8 into the upper cushioning material 7,
Since there are no protrusions around the refrigerator 50 until it reaches the lower end of the refrigerator 3, the box body 8 can be inserted extremely easily to the lower end of the refrigerator 3.

After inserting the box body 8 to the lower end of the refrigerator 3, a polyethylene bag is shrunk and inserted into the inlet body 10 from the rear side, and the inlet body 10 is inserted into the holes 13, 14.1 of the box body 8.
Insert into 5. Thereafter, although not shown, a nozzle for injecting urethane foam is directed to the injection port 11 of the injection port body 10, and the urethane foam is injected into the polyethylene bag 16 from the injection port 11. Then, the polyethylene bag 16 is pushed out from the injection port 11 into the box body 8 due to the injection of urethane foam, and gradually expands due to the foaming of the urethane foam, so that it comes into close contact with both the refrigerator 3 and the box body 8. .

After filling the polyethylene bag 16 with foamed urethane, injection of the foamed urethane is stopped and the cap 12 is placed over the injection port 11. In this way the hole 13.1 of the box body 8
The polyethylene bag 16 of the inlet body 10 fitted into the box body 8 is filled with urethane foam so as to fill the space between both corners of the back of the refrigerator 3 and both corners of the back of the box body 8. (This foaming and solidification of urethane constitute the cushioning materials 17 and 18. Also, the box body 8
polyethylene bag 1 of the inlet body 10 fitted into the hole 15 of the
The urethane foam filled in 6 fills the space between the compressor 6 and the back of the box body 8, and! The cushioning material 19 is formed by solidifying the urethane foam. Thereafter, the band 20 is wound around the bottom plate 1 and the box body 8 and tightened, thereby completing the packaging of the refrigerator 3.

The refrigerator 3 packaged in this manner buffers external forces that act in the vertical direction that occur when stacking and unloading, for example, by the secondary cushioning materials 7 and 2 on the top and bottom, and the cushioning materials 17 and 18 on both left and right sides of the back. This buffers external forces acting from the rear side to prevent dents on the back of the refrigerator 5, and the cushioning material 19 at the rear of the compressor 6 buffers shocks that act on the compressor 6 during transportation.

As described above, according to this embodiment, the cushioning materials 17, 18, and 19 can be provided after the box body 8 is placed on the refrigerator 6, so that when the box body 8 is placed on the refrigerator 3 as in the conventional case, the box body The problem of the lower end of the box body 8 getting caught on the cushioning material on both the left and right sides of the back of the refrigerator 3 or the cushioning material on the back of the compressor 6 and making it difficult to cover it is eliminated, and the box body 8 can be placed on the refrigerator 3 very easily. The cushioning materials 17, 18, 19 can be formed by a simple operation such as fitting the injection port body 10 into the holes 13, 14, 15 of the box body 8 and injecting foamed urethane from the injection port 11. The workability of j when packaging the refrigerator 3 is improved. In addition, conventionally this packaging work has been done manually, but as mentioned above, since the box body 8 can be extremely easily covered with the refrigerator 3, it is possible to automate the work of covering the box body 8. Furthermore, since the cushioning materials 17, 18, and 19 can be formed by the simple operation of directing the nozzle to the injection port 11 as described in 3 above, it is possible to automate this operation. It is possible to automate a series of packaging operations.

In the above-mentioned example, the cushioning materials 17 and 18 are provided on the back side of the refrigerator 5, but they may also be provided on the front side. Further, the present invention is not limited to the refrigerator 3, but can be widely applied to electrical appliances such as washing machines and dryers, and other articles.

〔Effect of the invention〕

As explained above, according to the present invention, an object to be packaged can be inserted into a wrapping ring without attaching a cushioning material to the object in advance. Therefore, unlike in the past, there is no longer a case where the packaging box gets caught on the cushioning material attached to the packaged item during insertion, hindering the storage operation, or causing the cushioning material to become damaged.
It can be inserted extremely easily and there is no risk of damage to the cushioning material.

In addition, the cushioning material can be sewn from the injection port to improve the ease of handling inside the bag.
