Description

This invention relates to a machine for manufacturing foam-processed cushioning paper that has the same cushioning properties as air bubble cushioning material by pressing elastic paper.

Traditionally, when there are gaps in containers such as cardboard boxes, various protective packaging methods are used to fill the gaps with cushioning material.

As a cushioning material for such protective packaging, packaging bubble cushioning material made of synthetic resin with air bubbles inside is widely known. An example of a synthetic resin is polyethylene. And an example of packaging bubble cushioning material made of synthetic resin with air bubbles inside is, for example, Patent Document 1.

Alternatively, polystyrene foam used for packaging machinery is also widely known as a cushioning material for protective packaging.

However, in recent years, there has been a demand for environmentally friendly cushioning materials in response to the SDGs.

It is preferable that the web-like paper is a foldable paper that has perforations formed at predetermined intervals and is folded at the perforations.

It is preferable that the device is provided with a paper holder for holding down the foldable paper, and by holding down the foldable paper with the paper holder, the foldable paper is divided at predetermined lengths along perforations.

It is preferable that the web-like paper is rolled paper.

It is preferable that the web-like paper be recycled kraft paper that has elasticity.

It is preferable that an emergency stop button is provided to stop the movement of the opposing first and second embossing rolls.

This invention has the remarkable effect of providing a foam-processed cushioning paper manufacturing machine that can produce environmentally friendly, recyclable cushioning material that can function as a cushioning material in the same way as synthetic resin packaging bubble cushioning material that has air bubbles inside.

1 is a schematic perspective view showing the principle of how foamed cushion paper is produced by the foamed cushion paper making machine of the present invention; FIG. 1 is a perspective view of a foam cushioning paper making machine according to the present invention; FIG.

One embodiment of the present invention will be described below with reference to the accompanying drawings. It goes without saying that various modifications and variations of the embodiment are possible without departing from the technical concept of the present invention. Note that the same members are indicated by the same reference numerals.

In the figure, the reference numeral 10 indicates one embodiment of the foamed cushioning paper manufacturing machine of the present invention. The foamed cushioning paper manufacturing machine 10 actually has an external appearance as shown in FIG. 2, but FIG. 1 shows only the essential parts.

As shown in FIG. 1, the foamed cushioning paper manufacturing machine 10 has an insertion opening 14 for inserting a web-like paper 12 having elasticity, a first embossing roll 20 having a number of foamed protrusions 18 on its circumferential surface for forming a number of foamed recesses 16 on the web-like paper 12 inserted through the insertion opening 14, and a second embossing roll 24 provided opposite the first embossing roll 20 and having a number of foamed protrusions 22 on its circumferential surface for forming a number of foamed recesses 16 on the web-like paper 12 inserted through the insertion opening 14. The elastic web-like paper 12 may be a folding paper or a rolled paper.

The numerous bubble-shaped convex portions 18 of the first embossing roll 20 and the numerous bubble-shaped convex portions 22 of the second embossing roll 24 are arranged in a staggered manner to prevent collision, and the web-like paper 12 is pressed by passing between the opposing first embossing roll 20 and second embossing roll 24, and a bubble-shaped processed cushioning paper 26 is produced in which numerous bubble-shaped recesses 16 are formed over the entire surface of the web-like paper 12. The numerous bubble-shaped recesses 16 are numerous hemispherical depressions. The first embossing roll 20 and the second embossing roll 24 can be made of plastic or metal.

In FIG. 2, the reference numeral 28 denotes the housing of the foamed cushioning paper manufacturing machine 10. Inside, the machine is equipped with the first embossing roll 20 and the second embossing roll 24. The web of paper 12 is inserted in the direction of the arrow in FIG. 2 to produce the foamed cushioning paper 26.

Reference numeral 30 denotes a power switch. Reference numeral 34 denotes an emergency stop button for stopping the movement of the opposing first embossing roll 20 and second embossing roll 24. In order to prevent accidents caused by entanglement, the emergency stop button 34 for stopping the movement of the opposing first embossing roll 20 and second embossing roll 24 is provided.

In FIG. 3, the foamed cushioning paper manufacturing machine 10 is equipped with a paper holder (not shown) on which the elastic web-like paper 12 is set. The web-like paper 12 may be a foldable paper that is perforated at a predetermined length and folded at the perforations. When foldable paper is used, a paper holding unit for holding down the foldable paper is attached to the paper outlet 38 of the foamed cushioning paper manufacturing machine 10 in FIG. 2 (not shown). Then, by holding down the foldable paper with the paper holding unit, the foldable paper can be configured to be divided at the perforations at predetermined lengths. As the paper holding unit, various known paper holding units can be used.

The web-like paper 12 may be any type that is in a web shape, and may be rolled paper other than the illustrated example. In the case of rolled paper, the center of the rolled paper is inserted into the hanging rod 40 of the paper holder 36 and hung so that it can be unwound. Also, an automatic outlet cutter can be installed at the outlet, allowing the discharged foamed cushioning paper 26 to be cut to an appropriate length. In this case, it is also possible to set the cut length and number of sheets of foamed cushioning paper 26 to be cut.

In addition to the illustrated example, the foam-processed cushioning paper manufacturing machine 10 can also be configured to use either folded paper or rolled paper.

The web-like paper 12 is preferably made of elastic recycled craft paper. As elastic recycled craft paper, various types of known elastic recycled craft paper can be used.

The foamed cushioning paper 26 produced by the foamed cushioning paper manufacturing machine 10 can function as a cushioning material in the same way as packaging bubble cushioning material made of synthetic resin that has air bubbles inside.

In addition, because it uses paper, it is recyclable, making it an environmentally friendly cushioning material. Furthermore, recycled paper can be used sufficiently as a cushioning material, making it a cushioning material that is fully compatible with a sustainable society.

The foam-processed cushioning paper manufacturing machine 10 configured as described above can function as a cushioning material in the same way as packaging bubble cushioning material made of synthetic resin with air bubbles inside, and can safely produce environmentally friendly, recyclable cushioning material.
