Description

[Detailed description of the invention] (Field of industrial application) The present invention is to wrap loose items in a horizontally long rectangular parallelepiped shape by placing wrapping paper over the items to be packaged, which are lined up in a row. This invention relates to an overwrapping device for wrapping in a row.

(Prior Art) FIG. 1 is a packaging process diagram showing a conventional process and a packaging process according to the present invention, in which loose items are arranged in a row and wrapped in a rectangular parallelepiped shape.

In Figure 1A, wrapping paper 1 cut to a specified size is supplied above the articles 2, which are arranged in a line with five pieces touching each other, and when the articles 2 are pushed up in the direction of the arrow, they are arranged as shown in Figure B. The upper surface of the wrapped article 2 and the lower surface of the wrapping paper 1 are in contact with each other. Next, fold the wrapping paper 1 on both sides of the article 2 in the longitudinal direction as shown in Figure C,
Fold and form the remaining side surfaces of both ends as shown in Figure D, then make the bottom of both ends into the form shown in the fold-out figure E, then fold the wrapping paper pieces on the longitudinal sides to the bottom as shown in the fold-out figure, and then form the remaining sides as shown in the fold-out figure. The side wrapping paper pieces are folded and adhered to the bottom to complete the overwrapping in the shape of an oblong rectangular parallelepiped as shown in the figure.

FIG. 2 shows examples of packaging articles 2 of different shapes.

Conventionally, a packaging apparatus for the above-described packaging order has been implemented using an apparatus as shown in FIG.

The perspective view shown in FIG. 5 shows only the main parts of the packaging device, and in this conventional device, a single horizontally long rectangular parallelepiped article 12 shown in FIG.
Although it is possible to package items according to the packaging order shown in the figure, it is impossible to package a plurality of articles 2 arranged side by side as shown in Figure 1A. The reason for this is that the lined articles 2 collapse during the packaging process, and this is because the conventional packaging apparatus has a structure that makes it impossible to wrap the lined articles 2. This will be explained using the conventional apparatus shown in FIG.

Five articles 2 arranged side by side are fed onto the presser 3, the wrapping paper 1 is placed on top of them, and the upper presser 11 is lowered to form the wrapping paper 1 and the lined up articles 2 as shown in FIG. When the push-up tool 3 is inserted between the molding frames 18' and 18'', the molding frames 18' and 18'' are passed between the guide plates 16' and 16'' and stopped above the square holes 15, resulting in the form shown in FIG. The horizontal folding plates 9, 9 are folded toward the bottom of the article 2 to fold and support the wrapping paper pieces of the articles 2 at both ends, and then when the push-up tool 3 descends, the three objects 2 in the center are 5 descended and lined up with
The articles 2 collapse and become impossible to package. For this reason, in the conventional device, the articles 2 are arranged on a mount 20 having the same area as the articles 2 arranged as shown in FIG. However, even if the push-up tool 3 is lowered after folding and supporting both ends of the lower surface of the mount 20 with both horizontally folding plates 9, 9, the articles 2 arranged on the mount 20 will not remain on the mount 20.
Because it is supported by the packaging, the packaging can be completed without collapsing or falling.

(Problems to be Solved by the Invention) Conventional packaging devices require a mount 20 to package the lined-up articles 2, which has the drawback of requiring more time and effort during supply and increasing the burden of packaging costs. Ta.

The object of the present invention is to provide an overwrapping device that does not require a mount and can wrap loose items in a row.

(Means for Solving the Problems) The overwrapping packaging device of the present invention, which arranges and packages loose items in a line, supplies articles to be packaged in a line on a push-up tool, and places wrapping paper on the articles. When the wrapping paper and the article are stopped slightly above the square hole by passing through the square hole of the forming frame, the upper presser and the upper presser are raised. After activating a pair of horizontal folding plates and a bottom folding plate that move horizontally from three sides along the bottom surface of the product, it moves to the other one and heat seals the overlapping surface of the wrapping paper on the bottom surface of the product to form a horizontally long rectangular parallelepiped shape. In a packaging device for overwrapping, the forming frame has a pair of side plates that face each other so as to be retractable into the square hole, and the upper end of one of the side plates supports an article stopped above the square hole. The height of the other side plate is uniform, and the upper end of the other side plate has at least one protrusion corresponding to each article except for the articles at both ends, and has a height that supports each corresponding article, and the bottom folding plate teeth,
The tip is provided with a tooth-shaped protrusion that enters between the protrusions of the other side plate.

(Function) A plurality of articles are fed in a line between a pair of movable side plates. Then, the wrapping paper is supplied on top of it, and the upper presser descends from above to press the wrapping paper. Next, the push-up tool and the upper presser move up while sandwiching the article and the wrapping paper, pass the article through the square hole of the forming frame, and stop the article slightly above the square hole. The side plate opens at the top while the article is passing through, and closes to support the bottom surface of the article after passing, pressing both edges of the wrapping paper, and this holding state is maintained even when the pusher and upper presser move back. . For this reason, multiple items can be wrapped in the wrapping paper in a cylindrical shape without falling apart, so that the three hanging edges of the wrapping paper can be wrapped around the items by the pair of horizontal folding plates and the bottom folding plate. Folded along the bottom surface.

The upper end of one of the side plates is tooth-shaped, and the tip of the bottom folding plate is also tooth-shaped so as not to interfere, so the bottom folding plate can be folded.
