DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of packing and packing flat products in an octagon so that flat products such as tempura can be accommodated in a circular container. Packaging method.

[0002]

2. Description of the Related Art Conventionally, ingredients such as tempura to be stored in a container of instant cup ramen are packaged by a horizontal bag making and filling machine, and the four corners of the bag are folded and completely stored in the container.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and can be octagonally flat-packaged so that a flat product can be accommodated in a circular container. It can be packed in an instant cup ramen container and packed in a square shape, eliminating the problem of folding the four corners of the bag into a container. It is intended to provide an octagonal packaging method.

[0004]

According to the present invention, a packaging film F is hung on a bag making machine 1 and bent into a tubular shape.
The packaging tube H is formed by center-sealing the edges f1 on both sides of the packaging bag H together, and the flat products S are fed into the packaging tube H from the opening of the bag making machine 1 at regular intervals by the product feeding conveyor 2. In the horizontal bag-making filling-packing method of a flat product in which the end products of the packaging tube H are end-sealed and cut by the end-seal cutter 4, the end-seal cut is performed at a position where the heater width corresponds to the center of the bag width. Symmetric box motions M1 and M2 are applied to a pair of heater blocks 4a and 4b, which are narrow and parallel and the heater width is gradually increased toward the upstream and downstream sides toward both sides, so as to end seal between the products of the packaging tube H. S, and a cutter 4c having a single blade shape and a V-shaped bifurcated shape on both sides corresponding to the V-shaped spread on both sides of the heater block 4a. , There is provided a method for the end seal S and wherein cutting the width center part of, packaged in the octagonal planar shape of the bag in the horizontal bag filling and packaging method of the flat products.

[0005]

FIG. 1 shows a method of packing a flat product in an octagonal plane in a horizontal bag making, filling and packaging method according to a first embodiment of the present invention. The packaging method of this embodiment is as follows.
The packaging film F is hung on the bag making machine 1 to be bent into a tubular shape, and the edges f1 on both sides of the packaging film F are fitted together with the film pulling roll 5 and pulled in. The center-sealer (a pair of heat rolls) The packaging tube H is formed by performing center sealing (heat sealing) at 3 and flat products w such as tempura are fed into the packaging tube H at regular intervals from the opening of the bag making device 1 by the product feeding conveyor 2, The end seal cutters 4, 4 end seal and cut (heat seal) between the products in the packaging tube H.

A feature of the packaging method of this embodiment is that the width of the heater corresponds to the center of the width of the bag as the end seal cutter 4 in order to package the bag so that the plane shape is substantially octagonal. A pair of heater blocks 4a and 4b are used which are narrow and parallel at the point where the heater width is gradually increased toward the upstream and downstream sides toward both sides, and a box motion M1, which is symmetrical to the pair of heater blocks 4a and 4b. M2 is applied to provide an end seal S between the products of the packaging tube H, and is enclosed in the upper heater block 4b, the central portion corresponding to the central portion of the heater block 4b and having a single blade shape. A cutter 4c having both ends formed in a V-shaped bifurcated shape corresponding to the V-shaped spread of both ends of the heater block 5 is used, and a box motion M2 is applied to the cutter 4c. Then, the end seal S is cut into the width central portion of the end seal S by penetrating into a cutter escape groove 4a 'engraved on the sealing surface of the lower heater block 4a in a shape corresponding to the cutter 4c. As a result, the packaged product A becomes substantially octagonal and fits completely in the circular container B without bending the corners of the bag.

FIG. 2 shows a method of packing a flat product in an octagonal shape in a horizontal bag making, filling and packaging method according to a second embodiment of the present invention. A feature of the packaging method of this embodiment is that end sealing and cutting are performed in two stages separately for an upstream station X and a downstream station Y. Symmetric box motions M1 and M2 are given to a pair of heater blocks 4a and 4b whose width is narrow and parallel at a position corresponding to the center of the bag width and whose heater width gradually expands toward the upstream and downstream toward both sides. Then, an end seal S is applied between the products of the packaging tube H, and then the downstream station Y
In the above, a cutter 4c having a single-blade central portion corresponding to the central portion of the heater block 4a and both ends extending in a V-shape, and both sides corresponding to the cut shape of the cutter 4c having a V-shape. Receiving plate 4d with expanding slit 4d '
Symmetrical box motions M3 and M4, and the cutter 4c and the receiving plate 4d cut the end seal S from the center of the width, so that the packaged product A becomes substantially octagonal. , Round container B without bending the corner of the bag
Fits inside. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

[0008] The horizontal bag making, filling and packaging method according to the present invention also includes reverse pillow packaging.

[0009]

As described above, according to the method of packing and wrapping a bag in an octagonal shape in the horizontal bag making and filling method of the present invention, a flat product can be accommodated in a circular container. Flat octagonal horizontal bag making and filling can be done.
Therefore, for example, an ingredient such as tempura can be packed in a flat octagon and packed in a container of instant cup noodles, and the manual operation of folding the four corners of a bag and storing it in a container can be eliminated.
