Abstract

PURPOSE:To enable uniform mass-production and manufacturing of a precise matter by a method wherein bent layers comprising divided parts bent in an arbitrary form and at arbitrary intervals by pulling out a sheet of an arbitrary material wound up around a paper roll are laminated in series for formation. CONSTITUTION:Base paper P is wound around a base paper roll R, a heat- weldable adhesive agent is kept applied to a plane of the base paper P, belt- shaped base paper 10 cut into a width capable of making into a desired height of a structural body with a slitter is supplied to a square-shaped jigs J11-J34 which are made into a state so as to conform to a lateral and longitudinal sides 12, 13. Then the jigs J11-J34 are caused to abut against the same, a base and each lateral sides 11, 12 are heat-welded through heating, according to which three-layer structural body comprised of layers S11-S13 is molded simultaneously. With this construction, the title tructural body is demarcated by the base, lateral and longitudinal sides 11, 12, 13 through a roll of the belt-shaped base paper 10 and the structural body can be formed in series as three layers hereupon.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves bending a strip of sheet material such as paper, resin, metal foil, etc., in a series of strokes in arbitrary shapes and intervals, and stacking folded layers. The present invention relates to a method of manufacturing a partition structure to be formed.

[Prior Art] Conventionally, a band-like sheet of kraft paper or the like is generally used for the partitions used in packaging boxes, and the folded portions formed by sequentially bending the sheet as many times as possible into a cross-sectional shape or a U-shape are attached to each sheet. A partition frame is created by bending both ends of a partition piece that is glued together to form each layer, or a partition piece made of paperboard material, and gluing an arbitrary number of them to a substrate to divide each layer into a square shape. , ]
, partitions are provided in which the side members of the shape are sequentially glued together to form a four-sided enclosure, or partitions are formed by gluing and assembling each section and each layer. It takes a lot of effort and cost to manufacture, and
Due to the manufacturing method, there are problems such as the shape of the partitioned portion being limited to the shape of an opening.

[Problems to be Solved by the Invention] Therefore, the present invention provides a method in which, in the conventional method, each side member of the partition portion is bonded, each side member is bonded to the partition substrate, and further, Even when forming layers, each layer is repeatedly bent in a U-shape and each layer is glued to a sheet, so it has not been possible to uniformly manufacture large quantities of arbitrarily shaped sections in a series. It is an object of the present invention to solve this problem and provide the same.

[Means for solving the problem, that is, the method of manufacturing the partition structure of the present invention is to draw out a sheet of any material wound around a paper roll or the like, and fold it into any shape and at any interval to form partitions. Since it is formed by laminating a series of bent layers, it has the advantage of being easily and uniformly mass-manufactured.

[Function] The method for manufacturing the partition structure of the present invention configured by the above-mentioned means sequentially draws out a band-shaped sheet material made of paper, resin, metal foil, etc. wound around a paper roll or the like, and shapes it into an arbitrary partition shape. Place it in the jig.

Desired layers can be easily formed at the same time by supplying the material and molding it by bringing it into contact with the jig.

Furthermore, by forming fold lines such as perforations in advance on the band-shaped sheet material in accordance with the shape of the partition, it can be formed very easily and accurately depending on the material, sheet thickness, etc.

[Example] In order to further clarify the gist of the present invention, one example will be described below with reference to the drawings.

To explain the first embodiment according to FIG. 1, a base paper P is wound around a base paper roll R, a heat-weldable adhesive is applied to the flat surface of the base paper P, and a slitter (not shown) The strip-shaped base paper 10 cut to the desired width for the desired height of the structure is fed to the opening-shaped jigs Jll to J34 that are designed to fit the horizontal sides 12 and vertical sides 13, and By bringing the jigs Jll to J34 into contact with each other and heating them, the main difference 11 and each of the horizontal sides 12 are thermally welded, so that a three-layer structure consisting of layers S11 to S13 is simultaneously formed.

Here, we have described the case in which a single strip of base paper 10 cut from the base paper roll P is formed, but the strip of base paper 10 cut into an arbitrary number is simultaneously cut between the jigs Jll to J34 as described above. If the structure is supplied to the jigs and heated through the jigs Jll to J34, the structure as described above can be simultaneously formed and taken out from the jigs Jl to J34 and used as appropriate.

In this way, - a large difference 11 depending on the wooden strip base paper 1o;
It is divided by horizontal sides 12, vertical sides 13, etc., and has been formed in a series as three layers.

Further, a second embodiment will be described according to FIG. 2. Similarly to the first embodiment, a strip-shaped base paper 10 that has been wound around a base paper roll R and cut to a desired width is held in a cylindrical jig J as shown in the figure.
21-J45 is supplied between a group of jigs arranged in a staggered manner, and then moved so that the upper and lower jigs come into contact with each other, and by heating, each base paper 10 in adjacent portions is thermally welded. Therefore, the connecting side 12c and the arcuate side 13c form a circular shape! ! Layers 321~ formed in series in a JI shape
The four-layer structure of S24 is formed at the same time, and similarly to each of the above embodiments, it can be taken out from the molds AJ21 to J45 and used as appropriate.

Furthermore, if the fold lines are made roughly as in the first embodiment, especially when the jig as mentioned above is not required,
The band-shaped base paper 1o is formed with the necessary fold lines for folding, and this is also manufactured using a simple press or the like.

Note that the shape, number, and size of each layer are not limited to those in the above embodiments, and the material used may be paper, or may be made of synthetic resin, gold leaf sheet, etc. 1. The method of the present invention may be arbitrarily determined within the scope of achieving the above-mentioned objectives, functions, and effects of the invention described below, and any of these changes shall not change the gist of the present invention in any way. Needless to say, it is not.

[Effects of the Invention] As described above in detail, the present invention involves pulling out and feeding a sheet of paper resin, gold foil material, etc. wound around a winding roll to a molding section consisting of a jig, etc. By forming partitions of different shapes and stacking them in series, a partition structure with partitions of arbitrary shapes can be manufactured extremely easily and at low cost with less manufacturing effort. Become.

Therefore, it is possible to uniformly mass-produce products with arbitrary section shapes or with precision.

Furthermore, since the invention is formed with a series of bends in a brush-like shape, it can be manufactured with great strength, and it is also possible to use other types of cores such as paper cores, etc. The present invention has excellent effects. be.
